Aesthetic Justifications for Music Education: a Theoretical Examination of Their Usefulness
Justifications for music education have been studied only by examining historical trends in statements of aesthetic versus utilitarian values, and not from the perspective of evaluating the justifications' usefulness. A number of prominent writers in the music education field, while supporting aesthetic values as important for music education, have expressed doubts about the effectiveness of aesthetic justifications when used for convincing outsiders of the importance of music in the public school curriculum. These doubts, along with a preponderance of aesthetic justifications in the recent music education literature, led to the present study, which conducted a theoretical examination of the usefulness of aesthetic justifications for music education. The study addressed three research problems, namely: (1) the attitudes of the clientele groups of the public schools in terms of their values toward music as a subject in the schools; (2) the attitudes of the groups within the music education profession in terms of their values for music in the public schools and for the profession itself; and 3) the likelihood that justifications based upon "aesthetics" as a system of values would be accepted by the groups both inside arid outside the music education profession. A philosophical-sociological perspective was chosen for the theoretical analysis because the problems of the study concern the manner in which values are accepted or rejected by groups of people. The particular sociological theory chosen combined the symbolic interaction theory of George Herbert Mead and the sociology of knowledge as described by Peter Berger and Thomas Luckmann. Conclusions: Problems arise in justifying music education using aesthetic theory because (1) the symbolic universe of aesthetic theory is complex and is not well-understood by music educators or the clientele of the public schools; and (2) aesthetic theory represents gestures of a reference group with norms and values not usually found in ...
American Indian Music in Elementary School Music Programs of Oklahoma : Repertoire, Authenticity and Instruction
The purpose of this study was to determine the instructional methods of Oklahoma's elementary school music educators with respect to the inclusion of an authentic repertoire of American Indian music in the curriculum. The research was conducted through two methods. First, an analysis and review of adopted textbook series and pertinent supplemental resources on American Indian music was made. Second, a survey of K-6 grade elementary music specialists in Oklahoma during the 1997-1998 school year was conducted.
The Application of Hackman and Oldham's Job Characteristic Model to Perceptions Community Music School Faculty Have Towards Their Job
Hackman and Oldham's Job Characteristic Model was applied to study of perceptions community music school faculty hold towards their job. The research questions addressed core job characteristics of skill variety, task identity, task significance, autonomy, and feedback, critical psychological states (experienced meaningfulness, experienced responsibility, and knowledge of results); personal and work outcomes of satisfaction and motivation; need for professional growth. The results were compared to the national norms for nine different job families provided by Oldham, Hackman, and Stepina. Thirty-three schools, all members of the National Guild of Community Schools of the Arts, located in every geographical region of the United States, yielded 437 faculty responses (64% return rate). Of the core job characteristics, dealing with others and autonomy received the highest ratings; feedback and task significance received the lowest ratings. Of the psychological states, experienced responsibility yielded the highest rating and experienced meaningfulness yielded the lowest ratings. Of the personal/work outcomes, personal development and colleague relations received the highest ratings; pay satisfaction and overall general satisfaction received the lowest ratings. A comparison to the professional job family norms, using a one-sample ttest, found significant differences in 16 out of the 18 variables measured by the Job Characteristic Model. Strong positive feelings for growth combined with less than strong feelings for the core job dimensions yielded a low motivating potential score of 96.18.
An Attitude Assessment of Amateur Musicians in Adult Community Bands
The purpose of this study was to ascertain certain factors which lead adults to participate in community band activity. This study attempted to answer the following questions: 1. What are the factors of rewards for community band participants based on the responses of a selected sample to validated attitude statements? 2. What are the relationships that might exist between certain demographic characteristics of the sample such as age, gender, education, occupation, musical training, geographic region (independent variables) and factors of participation (dependent variables) determined by principal components analysis? 3. What are the relationships that might exist between the findings of this study using member generated attitude statements and the findings of other attitude studies using researcher generated attitude statements? A 179-item survey was developed from an initital pool of 839 attitude statements after two pilot studies and an expert review. A randomly selected, stratified cluster sample of 74 organizational members of the Association of Concert Bands participated in the study. The average number of band members present during the survey process was 35. The average number of surveys returned per band was 23.66 for a return rate of 65.9% One thousand seven hundred twenty five individuals participated in the study. Frequency distributions of responses revealed the 36-50 age group to be the most represented (33%) followed closely by the 51-65 age group (27.8%). Males outnumbered females (57.5% to 42.3%). Over 80% of respondents were married. Almost 75% of respondents were college graduates. Over 60% had performed in college ensembles. Over half (55.4%) of respondents were either employed in the professional trades or white collar occupations. Almost 10% considered themselves professional musicians. Principal components analysis of the 179 items yielded six main factors of participation which were labeled Intrinsic Motivators, Organizational Motivators, Membership Standards, Repertoire/Conductor, Rehearsals/Performances, and Quality. Further analysis of ...
Attitudes of International Music Students from East Asia toward U.S. Higher Education Institutions
Nine universities in the United States with the greatest number of international students and having an accredited music program through the National Association of Schools of Music (NASM) were selected. Survey research methodologies were used to identify the status of the international music students from East Asia in U.S. higher education institutions and to determine their attitudes toward their schools. Among East Asian international music students at US higher education institutions, the results indicated that the professor's reputation, scholarships, and the program's reputation were perceived as the most influential factors impacting the program choice; a good relationship with professors, good feedback from professors, and emotional stability were perceived as the most influential factors impacting academic success; and the professor's teaching, the professor's expertise, and the improvement of musical skills were perceived as the most influential factors impacting students' satisfaction level. The most problematic issues reported were the language barrier and the cultural differences between their host and own countries. In addition, many of the East international music students in this study noted financial difficulties.
The Beginning Piano Class at the College Level
The problem was to investigate current thoughts concerning the beginning piano class at the college level, Data were collected from published and unpublished materials from 1964 to 1976. It was found that class piano instruction usually occurs in a three- to four-semester sequence, with classes meeting from two to five periods per week, containing from four to twenty-five students. Classification of students is by interview, placement test, and/or audition. Varying room arrangements are used with either conventional or electronic pianos, plus a variety of audio-visual equipment, Course content, with varying emphases, includes sight-reading, functional skills, technique, and repertoire. Teaching techniques used are numerous and varying. Recommendations were submitted for administrators, teachers, and researchers.
The Beginnings of Music in the Boston Public Schools: Decisions of the Boston School Committee in 1837 and 1845 in Light of Religious and Moral Concerns of the Time
The research problems of this dissertation were: 1) A description of the perceived value of music in light of political undercurrents in Boston prior to and during the years under investigation, and 2) the profile of the constituency of the Boston School Committee and Committee on Music in 1837 and 1845. Questions addressed the effect of religious and moral concerns of the day on the decision by the School Committee in 1837 to try music in the curriculum, and the possible effect of religious politics on Lowell Mason's dismissal from the schools in 1845. In the minds of mid-nineteenth century Bostonians, religious and moral values were intrinsic to the very nature of music. Key members on the School Committee portrayed music as being spiritual yet nonsectarian in its influence. Therefore, the findings suggest that music was believed to provide common ground between opposing and diverse religious sects. Reasons given for Mason's dismissal by John Sargent, a member of the Committee on Music, showed parallels to H. W. Day's accusations in the press a year earlier that Mason had managed his position in a sectarian manner. Sargent's background supports the theory that religious politics were at work in Mason's dismissal. Although members of the School Committee of 1845 were religious, only isolated cases support the proposition that any of them would have opposed Mason strictly on the basis of religious issues. Evidence suggests that their passivity to the action by the Committee on Music was probably due to concurrent public criticism of attempts at school reform within the Committee. While under such scrutiny, Committee members' inaction regarding Mason's dismissal may have reflected a desire not to jeopardize their own positions as a political body.
The Benefits of Adult Piano Study as Self-Reported by Selected Adult Piano Students.
The purpose of this study was to assess the benefits that selected adult piano students reported receiving from their study. Adult piano students (N = 711) from 24 states representing all geographic regions of the U.S. each completed a questionnaire containing 31 individual benefit items. These benefits were organized into 3 categories: Personal, Skill, and Social/Cultural. The demographic characteristics of the study population were consistent with the findings of other adult music research. Students indicated the existence (yes or no) of each benefit and rated the importance of existing benefits on a scale of 1-10. The category of Skill Benefits was the most agreed upon and highest rated category in the study, with over 90% agreement for each of the 7 Skill Benefits. The 14 Personal Benefits were also rated highly, particularly benefits related to self-actualization and fun. Self-related Personal Benefits were rated moderately, while more introverted Personal Benefits such as Imagination/Creativity, Spirituality, and Aesthetic Appreciation were lower rated benefits. The 10 Social/Cultural benefits were the lowest rated and least important benefits in the study. The most agreed upon benefits were Skill Improvement, Musical Knowledge, Musicianship, Accomplishment, Skill Refinement, Technique, Play/Fun, Escape from Routine, and Music Listening. The highest rated benefits in terms of importance were Dream Fulfilled, Technique, Accomplishment, Escape from Routine, Skill Improvement, Musicianship, Musical Knowledge, Play/Fun, Skill Refinement, and Personal Growth.
Caro Carapetyan: His Choral Beliefs and Practices
The purpose of this study was to identify and describe the convictions about choral conducting is held and applied by Caro Carapetyan which may have contributed to his superior choral work. The primary source of information was a series of personal interviews with Carapetyan. The report was organized into five sections. The first part supplied background material. Subjects covered in the report include philosophy, the relationship between conductor and singers the conductor's knowledge of music history and literature, rehearsal planning, conducting technique the selection of singers, choral tone, blend and balance, diction, intonation, rhythm, and dynamics. Each of the chapters in Parts II, III and IV includes a summary and some comparisons with other choral music sources. The fifth part is a summary of the findings, conclusions, and recommendations. Recommendations for choral conductors and future researchers are included.
A Case Study of Characteristics and Means of Person-to-Person Influence in American Kodály Music Education: Katinka Scipiades Dániel
The purpose of this study was to investigate the characteristics and means of Katinka Dániel's interpersonal influences through the perceptions of 20 selected students, protégés, and colleagues, and to study the behavioral and attitudinal changes they attributed to her influence. A case study design and structured interview questionnaire were used to study four variables coming from the social sciences' literature on influence: legitimate authority, attractiveness, expert authority, and trustworthiness. Responses were qualitatively analyzed to determine the role those variables played in Dániel's interpersonal influence. All interviewees were music teachers who used the Kodály method in their teaching and have studied or worked with Dániel. Two images of Dániel emerged from the interviews. The first, a business-like image, emanated from Dániel's work in the classroom, and the second, a maternal image, came from personal relationships with her students and associates. Attractiveness (defined as a willingness to respond positively to the requests of an influential person because one respects that individual and wants to obtain that person's approval) proved to be the principal characteristic of influence, followed by legitimate authority, then expertise. Trustworthiness played a lesser role. The greatest effect of Dániel's influence was on the interviewees' teaching. Among the factors interviewees described as influential were her expectation they would succeed, her position as role model, praise and encouragement, and gestures of generosity and concern. Interviewees were not in agreement as to whether she used persuasion or coercion. Direct verbal communication served a principal role in Dániel's influence, and though her criticism was described as forthright and bluntly honest, interviewees often accepted it. This was because most believed she was focused on their best interest, because her motives were not considered self-serving, and because they saw the reasons for her criticism as stemming from her high ideals and the desire to see ...
A Case Study of Interpersonal Influences in a Band Music Setting: Bohumil Makovsky (1878-1950) and His Association with Selected Individuals Involved in Instrumental Music in the State of Oklahoma
The purpose of this study was to investigate the interpersonal influences which Bohumil Makovsky, Director of Bands and Chairman of the Music Department at Oklahoma A&M College from 1915 to 1943, had on his students and peers, as confirmed through the perceptions of selected individuals, and to determine what personal characteristics and means he drew upon to induce changes in his students and peers.
The Centralized Higher Education System in Turkey and the National Music Teacher Training Program Since 1998: An Analysis.
The purpose was to analyze Turkey's current music teacher training curriculum as situated in the centralized educational system, focusing on the extent to which the written document (1) reflects the core elements of the overall centralized educational system; (2) prescribes the nature of teaching materials and methods, assessment tools and other forms of evaluating and monitoring performance as teachers and musicians; and (3) acknowledges cultural diversity by addressing repertoire, musical activities and concepts according to geographic and cultural regions. Qualitative-descriptive and quantitative content analysis, including the methods of (a) Inverse document frequency and (b) relevance feedback model, were the analytic tools. Of the required 147 credit hours, 138 are the core. The music core consists of 87 (63%) and the non-music core of 51 credit hours (37%). On paper, there is a conceptual overlap in wording between the music core, the general core, and the teacher training core, suggesting curricular cohesion and consistency. Noticeably less cohesion exists between the document and three major policy papers on teacher competencies. By word count, preparing teachers for instruction in Turkish folk music and multicultural issues appears to hold a low priority in the curriculum. However, course descriptions, where they exist, speak to skills and knowledge linked to performing and understanding Turkish folk and art music, not Western art music alone. Missing from those descriptions is any reference to teaching materials and methods, specific assessment tools, and other forms of evaluating and monitoring students. With reference to works by Max Weber, Karl Mannheim, and Robert Merton, the study concludes with a discussion about issues and problems inherent in a centralized teacher program that seeks to prepare music teachers for a culturally diverse society.
The Characteristics of Teacher-Directed Modeling Evidenced in the Practices of Three Experienced High School Choral Directors.
The purpose of this study was to analyze the characteristics of teacher directed modeling evidenced in the practices of three experienced high school choral directors. Research questions were: 1. What modeling activities were exhibited in each teacher's rehearsals? 2. When viewing a 45-minute composite tape of each teacher's instructional activities representative of all rehearsals, what instructional behaviors did each choral director recognize and identify as modeling? 3. What instructional episodes on the composite tape not identified by the teachers contained elements of modeling? 4. What other episodes from the remainder of each choral director's rehearsal practice contributed to an understanding of modeling? Videotapes of three high school choral directors were recorded over the course of one semester. Excerpts from rehearsals were combined to form a 45-minute composite tape of each choral director. A text transcription was made of the composite tape. Participant directors viewed their tape and identified instructional episodes that they recognized as examples of modeling. Identifications were analyzed, and descriptive categories of modeling behaviors were established. Modeling was found to be a teacher generated or delegated act of demonstration. Demonstrations were musical or non-musical and belonging to either of three distinct categories: audible, visible, or process modeling. Subdivisions of each category were found further describing modeling in the high school choral rehearsal. In addition, types of modeling were noted in increasing cognitive complexity required on the part of students beginning with simple imitation and concluding with models as tools for musical problem solving. Research is recommended on a larger sample of participants, including junior high/middle school directors to confirm categories and levels and to develop an observation tool based on results for describing, assessing, and modifying instructional techniques of practicing and pre-service music educators.
A Comparative Study of Two Choral Conductors: B. R. Henson and Lloyd Pfautsch
Although much has been written on the subject of conducting, it is generally recognized that a great deal can be learned through discussion with and observation of successful conductors. Direct contact with master conductors is an excellent learning tool, but seldom do high school or college choral conductors have the opportunity for direct individual study of the experts in their normal situations. This study provided the opportunity for one practitioner to work with two expert choral conductors. The report was written with the hope that other practitioners might also benefit from the results of the investigation. The purpose of this study was to identify and compare preparations and experiences, philosophies of music, and observable choral concepts which may have contributed to the superior choral achievements of B. R. Henson and Lloyd Pfautsch.
A Comparison of Aural and Visual Instructional Methodologies Designed to Improve the Intonation Accuracy of Seventh Grade Violin and Viola Instrumentalists.
The purpose of the study was to compare two instructional methodologies designed to improve the intonation accuracy of seventh grade violin and viola instrumentalists. The collection of data was in regard to (1) instructional methodology: aural and aural/visual, (2) performance tasks: A, B, and C; (3) individual pitches (seven from each of the music tasks), and (4) differences between instrument groups: violin and viola. Sixty-eight seventh grade string students from three string classes of two middle schools were randomly assigned to two experimental groups: (a) aural and (b) aural/visual. The instructional period was implemented daily in ten-minute sessions during twenty days by the orchestra instructors of each school. A pretest-posttest format was used to determine if there were any changes in the subjects' intonation accuracy from prior to after the instructional phase was implemented, and if these changes could be attributed to any of the methodologies. The testing material used on both testing sessions included three performance tasks composed of seven notes each. Subjects were recorded on both testing occasions. The data were the scores of absolute pitch deviation, measured in cents from equal temperament, from the pre- and postest; these were treated with analysis of variance. The ANOVA on the posttest scores indicated a non-significant difference between the instructional methodologies in their effectiveness to improve the subjects' ability to play in tune.
A Comparison of Major Theories of Laryngeal Vibration
The purpose of this study was to compare major theories of laryngeal vibration. The basic hypothesis of the study was that the differences and similarities between the major theories of laryngeal vibration could be made evident and clear through a comparative study. It was assumed that there are two or more theories of laryngeal vibration and that all the major theories of laryngeal vibration from 1945 to the present have been described in written form in English.
Compositions Designed to Improve Sight Singing in Junior High School
The purpose of this study was to identify certain aspects related to sight singing which tend to cause difficulty in teaching junior high school students and to suggest exercises that might be used to aid in overcoming these difficulties, Data included a questionnaire to junior high school teachers in three states. Subjects researched and discussed were the physical, intellectual, and emotional development of the adolescent; the changing voice and the range and vocal limitations of junior high singers; and rhythmic, melodic, harmonic, and other aspects of sight singing. Included were vocal procedures to be used with young voices, suggestions for choosing and/or arranging appropriate music, and original compositions designed to meet the needs and interests of junior high school students.
Constructions of Choir Identity in a High School
The purpose of this study was to investigate constructions of choir identity among high school choir students in the United States public school classroom setting. The research questions were (a) what are the processes involved in construction of choir identity and (b) how are the processes related to the group identity of the choir. The data were collected through participant observations in one selected choir classroom and semi-structured interviews with students from the choir class. The results included six processes of identity construction as well as identification of the ways in which each process was related to the choir group’s identity. The processes and their links to the overall choir group identity provided further insight into the ways in which high school choir students construct their identities, and they also supported methods of teaching commonly used in high school choir settings.
The Curricular Content of Elementary Music in China Between 1912 and 1982
The purpose of this study was to investigate the curricular content of elementary music in China between 1912 and 1982. The questions addressed were: (1) What changes in elementary music resulted from China's becoming a republic in 1912? (2) What changes in elementary music resulted from China's becoming a socialist country in 1949? (3) What changes in elementary music in the People's Republic of China resulted from the Anti—Rightist Struggle Movement in 1957? (4) What changes in elementary music in the People's Republic of China resulted from the Cultural Revolution (1966-1976)? (5) Have changes occurred in elementary music in the People's Republic of China since the beginning of the reform movement in 1978? (6) Did any of the changes affect curricular goals, contents, methods, required materials, and instruction time allotted in a like manner, or did some of these components remain the same while others changed? (7) Were the changes important enough to attribute them to a changed political ideology? After translating all pertinent documents, the goals, contents, methods, materials, and time allotted for the elementary music curricula between 1912 and 1982 were listed and identified. Subsequently, the areas of focus within those categories as well as changes in focus were identified and their importance determined. The findings were: (1) all important curricular changes occurred after 1950; and (2) changed goals resulted in changed teaching techniques; however, changed teaching techniques did not result in the changing of goals.
Dialogic Interactionism: the Construction of Self in the Secondary Choral Classroom.
Examined in this hermeneutic phenomenological study is a transformation in the researcher's choral music teaching in which students' abilities to construct self emerged organically from interactions, or dialogues, that took place among and between the students, the teacher, and the music being studied. To allow for such interaction to emerge organically and meaningfully, students and teacher both shared in the power needed to construct a classroom environment in which the localized issues of the classroom and the specific contexts of students' lived histories were maintained and encouraged. This process of interaction, based upon dialogue among and between equal agents in the classroom, is described in the study as dialogic interactionism. In order to examine the concept of dialogic interactionism, three constructs upon which dialogic interactionism is based were developed and philosophically analyzed. They include the construction of self through the construction of self-knowledge; the localized reference system of the classroom, and the issue of power. Each construct is considered within the context of extant writings both in general education and music education philosophy. Following the analysis, a theoretical description of the dialogic interactive choral classroom is given as well a description of how such ideas might be realized in practice. The study concludes with issues for further study.
The Effect of Ethnicity on the Age-of-onset of the Male Voice Change.
The purposes of this study were to describe the characteristics of the changing male voice in 4th, 5th and 6th grade students using Cooksey's maturation stages and, to compare the age-of-onset of the male voice change in African American, White, and Hispanic male students. Participants included volunteer 4th (n = 61), 5th (n = 73), and 6th grade male students (n = 63) from 2 urban elementary schools, 5 suburban elementary schools, 1 suburban middle school and 1 urban middle school in the North Texas region. The three ethnic groups represented in this study were: African American (n = 62), White (n = 58), and Hispanic (n = 77). Results indicated that approximately 46% of 4th grade participants, 62% of 5th grade participants, and 67% of 6th grade participants were classified as changing voices. A descriptively larger percentage of African American participants were classified as changing voices than Hispanic and White participants. Also, a larger percentage of African American and Hispanic participants were descriptively classified in the more advanced stages of the voice change than White participants. Urban African American, White, and Hispanic participants had a larger percentage of males classified as changing voices than suburban African American, White, and Hispanic participants. Results of a one-way, between subjects ANOVA revealed no significant main effect for ethnicity, F (2, 51) = .42, p = .66, η2 = .02. The overall mean age-of-onset for participants in this study was approximately 11.20 years of age.
The Effect of Individual Versus Collective Creative Problem Solving Experiences on Fourth- and Fifth-grade Students' Compositional Products.
The purpose of the study was to explore the effects that individual vs. collective structured creative musical problem solving tasks had on students' compositional products. Subjects in a convenience sample of 32 fourth-graders and 32 fifth-graders were randomly assigned to either the individual or collective condition. The 3 treatment sessions were characterized by an open-ended creative problem solving task, which included questions intended to guide subjects through 3 stages of the creative problem solving process: Understanding the Problem, Generating Ideas, and Planning for Action. Subjects participated in the pre- and posttest individually. Three experienced music educators assessed the compositional products in terms of pattern use, cohesiveness, and creativity. The originally intended MANCOVAs could not be carried out because the data did not meet the necessary assumptions. Pretest and posttest scores were explored with individual ANOVAs. The Bonferroni technique was used to adjust the alpha level. The statistical analyses showed that subjects exposed to the individual condition obtained higher scores than subjects exposed to the collective condition on six of the eight explored subtests, but these differences were not significant. The level of interjudge reliability decreased at each of the three measurements of the study: pilot test, pretest, and posttest. The study's results suggest that music educators interested in observing specific characteristics of individual students' compositional products, such as the levels of cohesiveness, creativity, and pattern use, could do so regardless of the condition under which students were exposed to compositional tasks, either individually or collectively. Recommendations for future research include the use of a measurement instrument specifically designed for open-ended tasks, and the exploration of the current study's measurement instrument with closed-ended tasks. The study highlights the need for appropriate measurement instruments designed for the compositional tasks at hand, and the need for research results reported clearly, so that more ...
The Effect of Three Compositional Structures on the Compositional and Instructional Self-efficacy of Pre-service Music Teachers
The purpose of this study was two-fold: 1) to compare the effects of three different composition tasks with varying degrees of structure on pre-service music teachers’ creative self-efficacy as composers and their instructional self-efficacy as pedagogues of composition; and 2) to describe through pre-service music teachers’ talk perceptions of composition and their experiences completing the three composition tasks. Participants (N = 29) were music education majors from three different sized universities in the northern-central region of the United States. At the beginning of the study, the participants answered a researcher-design self-efficacy questionnaire that measured (a) their self-efficacy as composers and (b) their self-efficacy as teachers of composition. Next, they composed three compositions of various task structures (unstructured, poem, and rhythm). Immediately after completing each task they again completed the self-efficacy questionnaire. Statistically significant mean differences between the pre-task administration of the measuring instrument and all three composition tasks were found for the pre-service teachers’ compositional self-efficacy. Statistically significant mean differences were also found between the unstructured task and the rhythm task, but not between the rhythm and poem tasks or the unstructured and poem tasks. For the pre-service teachers’ self-efficacy as pedagogues of composition question, the results were also statistically significant between the pre-task administration of the measuring instrument and all three composition tasks. Statistically significant mean differences were also found between the unstructured task and the rhythm task as well as the poem and rhythm tasks, but not between the unstructured and poem tasks. Additional data were gathered through semi-structured one-on-one interviews. Through their talk the pre-service music teachers commented that they enjoyed the overall composition process. This experience also seemed to challenge the participants’ assumptions about composition and appeared to make creative experiences more tenable and relevant to their future classroom experiences. The results of this study suggest ...
The Effect of Three Different Levels of Skill Training in Musical Timbre Discrimination on Alphabet Sound Discrimination in Pre-Kindergarten and Kindergarten Children
The purpose of this study was to investigate the effects of three different levels of skill training in musical timbre discrimination on alphabet sound discrimination in pre-kindergarten and kindergarten children. The findings of prior investigations indicated similarities between aural music and language perception. Psychoacoustic and neurological findings have reported the discrimination of alphabet quality and musical timbre to be similar perceptual functions and have provided, through imaging technology, physical evidence of music learning simultaneously stimulating non-musical areas of the brain. This investigator hypothesized that timbre discrimination, the process of differentiating the characteristic quality of one complex sound from another of identical pitch and loudness, may have been a common factor between music and alphabet sound discrimination. Existing studies had not explored this relationship or the effects of directly teaching for transfer on learning generalization between skills used for the discrimination of musical timbre and alphabet sounds. Variables identified as similar from the literature were the discrimination of same- different musical and alphabet sounds, visual recognition of musical and alphabet pictures as sound sources, and association of alphabet and musical sounds with matching symbols. A randomized pre-post test design with intermittent measures was used to implement the study. There were 5 instructional groups. Groups 1, 2,and 3 received one, two and three levels of skill instruction respectively. Groups 4 received three levels of skill training with instruction for transfer; Group 5 traditional timbre instruction. Students were measured at the 5th (Level 1), 10th (Level 2), 14th (Level 3), and 18th (delayed re-test), weeks of instruction. Results revealed timbre discrimination instruction had a significant impact on alphabet sound-symbol discrimination achievement in pre-kindergarten and kindergarten children. Different levels of timbre instruction had different degrees of effectiveness on alphabet sound discrimination. Students who received three levels of timbre discrimination instruction and were taught to ...
The Effects of Amplification and Selected Vocal Exercises on the Perceived Vocal Health of Elementary Music Educators.
The main purpose of this study was to consider the effects of amplification and vocal function exercises on the perceived vocal health of elementary music educators (N = 37) from Oklahoma (n = 11) and Texas (n = 26). Participants were assigned to the use of the ChatterVoxTM amplifier or vocal function exercises based on pretest scores on the Voice Handicap Index with Music Teacher Voice Questionnaire (VHI/MVQ). Following the 4-week study period, participants completed the posttest VHI/MVQ. The results of a one-way ANCOVA that used treatment group as the independent variable, the summed posttest scores as the dependent variable, and the summed pretest scores as the covariate or control variable indicated that there was a statistically significant difference between the adjusted means for the posttest scores, favoring the exercises group. The overall group and both treatment groups reported frequent loud voice use in work settings and in public places. The overall group and the amplification group reported hoarseness after prolonged talking. The exercises group did not report as great a problem with hoarseness after prolonged talking. Secondary purposes addressed demographic variables. Women perceived greater overall vocal difficulties than men; men frequently reported specific vocal complaints that were not commonly indicated by women. The vocal problems of women may have been associated with loud voice use. The following common vocal complaints of men may have been related to the use of falsetto while teaching: need for vocal rest, worse voices in the evening, dry throats, loss of voice, obvious pitch breaks in their singing voices, pain after singing for an extended time, and limited use of their high range. VHI/MVQ scores indicated that the study participants with 21 to 39 years of teaching experience had more vocal difficulties than other participants and indicated limited use of the low range of ...
The Effects of Free Play As an Instructional Tool on the Quality of Improvisation of First, Second, and Third Grade Children
To look at the effect of free play on the musical improvisations of first, second and third grade children, 108 children were randomly assigned to either a control or treatment group. Subjects were tested using a researcher-designed instrument to elicit an improvisatory response. The control group then received regular music instruction (120 minutes every 2 weeks) and the treatment group received regular music instruction in conjunction with musical free play (100 minutes of instruction and 20 minutes of free play every 2 weeks). The treatment lasted 14 weeks. At the end of the treatment, all students were tested with the same testing instrument used for the pre test. Videotapes of the improvisations were submitted to three independent judges to rate for quality on a 5-point Likert scale. The change in ratings between pre and post tests were analyzed with an analysis of variance to determine if there were significant differences between the control and treatment groups. The analysis of the data revealed no significant difference in the change of ratings between control and treatment groups for the group as a whole, or for any particular grade level within the total group.
The Effects of Instruction on the Singing Ability of Children Ages 5-11: a Meta-analysis
The purpose of the meta-analysis was to address the varied and somewhat stratified study results within the area of singing ability and instruction by statistically summarizing the data of related studies. An analysis yielded a small overall mean effect size for instruction across 34 studies, 433 unique effects, and 5,497 participants ranging in age from 5- to 11-years old (g = 0.43). The largest overall study effect size across categorical variables included the effects of same and different discrimination techniques on mean score gains. The largest overall effect size across categorical moderator variables included research design: Pretest-posttest 1 group design. Overall mean effects by primary moderator variable ranged from trivial to moderate. Feedback yielded the largest effect regarding teaching condition, 8-year-old children yielded the largest effect regarding age, girls yielded the largest effect regarding gender, the Boardman assessment measure yielded the largest effect regarding measurement instrument, and song accuracy yielded the largest effect regarding measured task. Conclusions address implications for teaching, research pedagogy, and research practice within the field of music education.
The Effects of Practice Procedure and Task Difficulty on Tonal Pattern Accuracy.
The study investigated the relative effectiveness of different proportions of time spent on physical and mental practice, in the context of a music performance of a tonal pattern over harmonic progressions of two difficulty levels. Using a sampling without replacement procedure, sixty undergraduate students were assigned to four practice groups partially blocked for musical instrument. The groups included a physical practice group, a mental practice group and two combined mental and physical practice groups in the proportions of (a) 66% physical and 33% mental, and (b) 33% physical and 66% mental. Each subject performed a pretest, a 3 minute practice session, and a posttest on both harmonic progressions. Presentation of the harmonic progressions were counterbalanced to control for practice effects All pre- and posttests were recorded and scored according to number of note errors. An ANCOVA procedure using pretest scores as covariates revealed that: (a) there were no differences between the different practice groups on the measure of note errors, (b) there was a significant difference between the two harmonic progressions on the measure of note errors, such that performance on the easy progression was significantly better than performance on the hard progression, and (c) there was a significant interaction between harmonic difficulty level and the practice groups. Post hoc comparisons between the adjusted means of the practice groups on the two tasks revealed that for the mental and the 33:66 combined practice groups, groups consisting of a higher percentage of mental practice, performance on the easy harmonic progression was significantly better than on the hard harmonic progression. However for the physical and the 66:33 combined practice groups, groups consisting of a higher percentage of physical practice, performance on both harmonic progressions was not significantly different and was as good as the performance of all practice groups on the easy ...
Elementary music teachers instructing English language learners: Reflection on practice.
This qualitative study investigated four monolingual, English-only speaking Caucasian elementary music teachers and their reflections regarding instruction of English language learners (ELL). The purpose of this multiple case study was to investigate the teaching practice and curricular decisions of elementary music teachers who instruct Hispanic ELL students. The investigation was conducted during a nine-week period, and data collection included classroom observations, phenomenological interviewing, and teacher audio journals. None of the teachers had prior education or pre-service preparation in teaching music to ELL students. The major theoretical base from which the study was developed was the reflective teaching theory of Donald Schön (1983). The main research question was: "What are the participating teachers' reflections about their curricular and pedagogical decisions when teaching ELL students?" Following a description of the elementary music teachers' reflections on practice with ELL students, the study revealed that the majority of elementary music teachers had a lack of preparation and ELL music curriculum, and negative perceptions of the placement program for ESL students. Despite these factors, the teachers made attempts to include ELL students in all music activities. This study showed that while one teacher accommodated specifically for the ELL students' learning, three out of four teachers did not. This study also suggests that music is a subject by which strong interactions between peers, opportunity for language expansion, and other factors occur which have positive correspondence to recommended ELL instructional strategies. A cross-case analysis revealed that the life history and experience of the elementary music teachers had an influence on the teachers' awareness of ELL students. The analysis suggests a relationship between teacher awareness and accommodation. The study also recognized the need for further inquiry regarding ELL students and issues related to their school placement. This study has implications for music education research including suggestions for music ...
An Examination of the Presence of Schön's Concept of "Reflective Conversation" as a Defining Component in the Applied Studio Music Lesson
The purpose of this study was to examine the presence of Schön's concept of reflective conversation as a defining component in the applied studio music lesson. The research problems were (1) to determine the presence of complete and incomplete reflective conversations; (2) to determine the verbally exhibited knowledge base within complete conversations in relationship to conversation length; and (3) to establish an instructional profile of stable behaviors based on reflective conversation as a distinguishing characteristic among selected teachers. Videotapes of twenty-six applied studio music lessons of thirteen university teachers were analyzed according to problem solving, on-the-spot experimentation, and evaluation. An observation form was developed and was a reliable tool to collect information concerning number and type of reflective conversations, conversation length, and the teachers' verbally demonstrated knowledge base. Knowledge base was obtained by using the procedural model of Flanagan's critical incident technique. Reflective conversations existed and were a distinguishing characteristic of the teachers. With the exception of two teachers, a stable use of both number and length of reflective conversations, and knowledge base areas, was found. A discernible difference in the teachers' knowledge base within conversation length existed, and thus established instructional profiles for the teachers. Complete reflective conversations ranged from one-sixth to over half of total lesson time. Within instrument categories, teachers generally revealed a dissimilar knowledge usage. Some teachers exhibited fast-paced problem solving, in one minute or less, and named one or two knowledge areas. Others had longer conversations, up to five minutes, with more deliberate problem solving, and as many as twelve knowledge areas named. Results indicated that a practically significant situation can be examined by establishing teacher instructional profiles based upon reflective conversation. Methods employed in this study could be used to document teacher problem-solving and teacher knowledge in a variety of settings.
Experiencing the interdependent nature of musicianship and educatorship as defined by David J. Elliott in the context of the collegiate level vocal jazz ensemble.
Examination of the relationship of musicianship and educatorship of teacher and students as interacting partners in a specific musical context proceeded with investigation of how formal, informal, impressionistic, and supervisory musical and educational knowledge were evidenced in rehearsal. Attention was also given to how the teaching strategies of modeling, coaching, scaffolding, fading, articulating, reflecting comparatively, and exploring were used to develop student musicianship. The research methodology may best be described as an inductive analytical case study approach. Multiple data sources included: videotaped observations of 19 bi-weekly rehearsals, audio taped interviews of the 12 participants, supplemental materials, (a published interview, journal articles, rehearsal schedules), and member checking with the teacher and David Elliott. Rehearsal data were initially organized into categories identified in David J. Elliott's (1995) model. The relationship of teacher and student musicianship, and teacher educatorship emerged during analysis. Musical details of problem finding, reducing and solving were also identified. Three themes emerged from the student interviews: their perceptions of the teacher's musicianship, general rehearsal strategies, and the teacher's use of specific teaching strategies. Interviews with the teacher illuminated his perception of musicianship and teaching strategies employed in the context. The findings confirmed that as music making transpired in the rehearsals, the kinds of knowing present in the musicianship of teacher and students and the teacher's educatorship were not only intertwined but were utilized at the same time. The level of student musicianship was allied to the relationship of the teacher's musicianship and educatorship. The intricate relationship between the kinds of procedural knowledge that Elliott identifies as integral to music making and music teaching are illustrated in a set of diagrams. Additionally, they show the wide range of technical and musical problems the teacher and students solved together in order for the multifarious nature of the vocal jazz repertoire to ...
Factors Relating to Student Participation in Public School String Programs
This study explored factors relating to participation in public school orchestra programs and the relationship and predictability of such factors in accordance with Maehr's theory of personal investment.
A Fourteen-Week Program for Teaching Beginning Music Reading Through Rhythmic Notation and Pitch Notation to Pre-School Children in Piano Classes
The purpose of this study is to develop a fourteen-week program for teaching beginning music reading through rhythmic and pitch notation to pre-school children in piano classes. The historical background for the study discusses man's learning abilities in the group process in music education with the particular reference to class piano and its development and publications by leading authorities concerning class piano and rhythmic training in the classroom. The second chapter contains analyses and summaries of five selected texts pertinent to the study. The findings of research of the five selected texts serve as the groundwork for the development of the program which is contained in the third chapter.
Functional Theory for Applied Music Students
The purpose of this study was to prepare music theory textbook-workbooks for students of elementary school grades four through eight who are taking private music lessons in voice, piano, or other instruments. The study was prompted by the action taken first by Texas Music Teachers Association and later by Music Teachers National Association which made the passing of comprehensive music theory examinations a prerequisite for entering all student performance and contest events sponsored by these associations.
The General Music Course in the Secondary School: A Content Analysis of Selected Curricular Sources
The study described through content analysis the general music course in the secondary school as perceived in selected curricular sources from the 1960's and 1970's. As various writers of curricular sources developed their own content and methodologies, a vast amount of data became available which seemed unmanageable because of the particular philosophical goals chosen for the course. The study organized in a systematic manner the content and methodologies of the.course by means of eighteen categories. Categories of high frequency inclusion in the general music sources were shown to be the elements of music, music vocabulary as a specific area for learning, the predominant choice of classical Western/art music, the use of listening and creative activities and the discussion of psychological learning principles.
High School Contemporary a Cappella: a Descriptive Phenomenology
This study examines the phenomenon of contemporary a cappella music making found in high school settings as curricular and extra-curricular offerings. Past music and music education literature has focused exclusively on contemporary a cappella at the collegiate level. Through application of a descriptive phenomenological method and incorporation an educational-sociological lens, this study advances an understanding of the educational benefit and social value of membership in contemporary a cappella at the high school level. Six recent members from three regions of the United States provided data through individual open-form interviews in which questions were derived from the participants’ own speech. I incorporated phenomenological reductions and processes to negate researcher bias during data collection, analysis, and the formation of a general structure and constituent meanings of membership in high school contemporary a cappella. Participants utilized traditional music skills, individual talents, conceptions of popular culture and music, and in-group socialization to facilitate music making and reify membership. Expressing the value of group membership, individuals acted to benefit the group by cultivating social bonds, developing and fostering personal/shared connections to songs, identifying and purposing individual talents and skills, and gaining an understanding of each members’ unique contribution to membership. Discussion includes implications for music education and suggestions for future research.
High school string orchestra teacher as a career choice: A survey of 11th- and 12th-grade high school string orchestra students in Texas.
The purpose of this study was to describe 11th- and 12th-grade high school string orchestra students in Texas public schools in terms of their decision to enter the field of string orchestra teaching as a possible career choice or to pursue another field of study. Convenience sampling techniques were used to secure a study population of 1,683 high school string orchestra students. The Junior and Senior High School String Orchestra Student Survey (researcher designed) was used to gather demographic characteristics, students' perceptions on selected intrinsic/extrinsic work values, tangible elements of teaching, intrinsic characteristics of string orchestra teaching, and individuals assisting in students' career choices. Selected elements of teaching cited by students for their lack of interest in string orchestra teaching were also reviewed. Analysis procedures for descriptive statistics included measures of central tendency, crosstabulation, frequencies and percentages. Consistent with prior research, it was found that a larger number of female students over male students were interested in string orchestra teaching. Students interested in fields outside of string orchestra teaching reported higher class grades, more honors and advanced classes and higher SAT/ACT mean scores. Students interested in string orchestra teaching reported a higher percentage of brothers/sisters, mothers and fathers who played instruments and relatives who were teachers. These students also reported a greater importance of a career that was self-rewarding, that would be directly helpful to society and where they could help contribute to the welfare of society. Students interested in string orchestra teaching expressed the great importance of their deep devotion to music and their desire to be a positive role model for children. Students interested in string orchestra teaching reported the great importance of their high school orchestra director as one of the individuals assisting them in their career decisions. Also consistent with prior research, the number one cited ...
Improvisation in the Beginning Piano Class
The problem was to survey and collect ideas on the use of improvisation as a teaching and learning tool in elementary piano instruction and to prescribe activities and exercises for second through fourth grade piano classes. These areas were examined: philosophies and theories influencing traditional instruction, effects of creative keyboard activities on children's musical development, specific teaching strategies using improvisation, evaluative procedures, and suitability of materials for young children. Data collected from published and unpublished materials were classified, and presented concerning the feasibility of using keyboard improvisation with early elementary children. It was found that suitable improvisational exercises allow the child to organize his perceptions into the basic concepts of music. Recommendations for teachers and researchers were made.
Independent Piano Teachers: An Investigation of Their Attitudes toward Selected Attributes of Profession
The purpose of the study was to investigate independent piano teachers' view of themselves in the light of selected attributes found in sociological writings on the professions. The research problems were: (a) to determine the attitudes which independent piano teachers held toward selected professional attributes; (b) to determine the relationship between the attitudes toward the professional attributes and selected background variables; and (c) to determine the degree of association between these attributes. The problems were addressed by a questionnaire directed to independent piano teachers active in the area of Dallas-Ft. Worth, Texas. Thirty teachers were also interviewed to determine consistency of response and to explore issues which the questionnaire had raised. Reliability and validity were established at acceptable levels. Techniques of statistical analysis included Pearson's product-moment correlation, multiple regression, chi-square in conjunction with Cramer's V_, and factor analysis. The strongest attitudes expressed by the teachers in the study concerned professional self-image, altruism, client orientation, commitment to work, and independence. The most important background variables were age, years of experience, number of students, certification by a professional association, and college degree in music. A multiple regression analysis tested each variable against the dependent variable professional self-image; recognition by others, commitment to work, client orientation, and qualification were found to account for 25% of the common variance. A factor analysis was also conducted to seek out patterns of attitudes among the attributes being studied; seven factors were identified among the subjects' belief systems as Professional Actions, Satisfaction, Quality Control, Professionalism, Compliance, Autonomy, and Focus on Student. These factors accounted for almost half of the total variance in the data. The study concluded that: (a) independent piano teaching was a female-dominated, subsidized occupation, and (b) the piano teachers' professional self-image seemed to be an evaluation of themselves and their work, rather than the ...
An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade
The purpose of the study was to determine whether students' timbre preferences in the sixth grade remain stable through the tenth grade. The investigation also examined whether gender, band instruction, or musical home environment makes any difference in influencing the stability of students' timbre preferences from grade six through ten. Students' timbre preferences at the beginning of the study were compared to their preferences four years later. The students' timbre preferences were obtained by employing Gordon's Instrument Timbre Preference Test (ITPT). A questionnaire was also utilized at the conclusion of the study to determine which students had musical home environments and which did not. All sixth grade students enrolled in a single school district took the ITPT. Each student's scores were tallied and ranked in order to determine their timbre preferences; four years later they were retested and their scores were ranked again.
An Investigation of Conflicts in the Perceptions of Band Directors, School Administrators, and Selected Members of the Community About Their Respective Band Programs
The purpose of the study was to investigate conflicts in the perceptions of band directors, band parents, band students, and selected school personnel regarding the role and scope of their respective band programs. The problems were to examine the relationships among these four groups in terms of selective perception, perceptual constancy, and polarization. Questionnaires were developed in order to survey the senior public high schools in Cedar Rapids, Iowa. In addition to demographic data, the questionnaires included perceptions about public performances, marching, concert, and jazz bands; contests and festivals; and other band related activities which might be desirable in a band program. The questionnaires concluded with opportunities for open-ended comments and suggestions about the survey instrument and the band program. Statistical computations included one-way analysis of variance, chi-square test, frequency counts, and cross-tabulations. Qualitative analyses and reports of interviews helped to clarify and interpret all statistical findings.
An Investigation of Heart Response During Trumpet Playing
The purpose of this study was to investigate the effects of trumpet playing upon the heart. A Holter monitor was used to record electrocardiograms (ECGs) to examine the heart's response during musical performances and practice sessions.
An Investigation of Holland's Theory of Vocational Personalities and Work Environments As Applied to Undergraduate Music Majors
Holland's theory of vocational personalities and work environments incorporates four theoretical constructs (congruence, consistency, differentiation and identity) which attempt to explain sources in variability of achievement and satisfaction among employed adults and college students. This study sought to: (1) investigate the relationship of Holland's constructs to academic achievement and educational satisfaction of undergraduate music majors; (2) investigate differences in all variables according to gender and degree major. Data were collected from undergraduate music majors (N = 100) enrolled at the University of North Texas using the Vocational Preference Inventory. Mv Vocational Situation. and the Music Major Satisfaction Questionnaire. Reliability for the Music Major Satisfaction Questionnaire was estimated at .92 using Cronbach's coefficient alpha. Pearson product-moment correlation coefficients indicated that: (1) congruence was significantly related to academic achievement and educational satisfaction; (2) identity was significantly related to academic achievement and educational satisfaction; (3) consistency was significantly related to academic achievement, but not to educational satisfaction; (4) differentiation was significantly related to academic achievement, but not to educational satisfaction. Multiple regression using a stepwise entry method indicated that: (1) the identity construct was the best predictor of educational satisfaction scores; (2) identity was the best predictor of academic achievement scores. The results of the study suggested: (1) it is unlikely that any single theory accounts for all dimensions of variability in achievement among college music majors. To arrive at a comprehensive model of achievement, it will be necessary to utilize constructs of several theories. Such a model should include Holland's constructs of identity, congruence, and possibly differentiation. (2) similarly, a comprehensive model of satisfaction should include Holland's constructs of identity and congruence. (3) Holland's classification system may distinguish among two traditionally held divisions of college music majors, performance majors and education majors. (4) music education majors and music performance majors differ on ...
An Investigation of Perception of a Frequency Modulated Band Location of Pitch Within a Musical Vibrato
The purpose of this study was to investigate aspects of pitch perception of auditors when presented with musical tones whose frequencies were modulated. Research problems were: estimation of the effect of musical training upon pitch perception; estimation of the effect of stimuli of differing tonal qualities and frequency ranges upon perception; and estimation of the effect of solo and ensemble performances upon pitch perception. Subjects for the study were thirty musicians and thirty nonmusicians. Subjects were students at North Texas State University and Paris Junior College who had volunteered for the study. A test containing thirty-six items was developed which required subjects to match a tone created by a sawtooth wave generator to a simultaneously presented musical tone performed with vibrato. Each subject was tested individually, and allowed three attempts to match each test item. After the third playing of each item, a reading was taken of the frequency selected by the subject, Using the split half method, reliability for the test was found to be .86 for nonmusicians and .88 for musicians. ANOVA evaluation of responses of subjects indicated that there was a significant difference.in the location of pitch among musicians and nonmusicians, with musicians locating the pitch somewhat higher in the frequency spectrum than nonmusicians. Neither group located the pitch of modulated musical tones at the geometric mean of the modulation. Differences located in responses of the groups were consistant with regard to stimuli of varying frequency levels and timbres, and were unaffected by either solo or ensemble performance of the stimulus. Subsidiary findings indicated that among musicians no significant differences in pitch perception may be traced to the major performing instrument of the subject; differences in these subgroups and nonmusicians were consistant with the findings comparing musicians as "a whole and nonmusicians. Suggestions were made concerning application ...
An Investigation of Personal Investment Levels Among Nonmusic Major Piano Students Using Portfolio Assessment
The purpose of this study was to compare personal investment levels among nonmusic major piano students in the contexts of portfolio and teacher-directed assessment. Three problems were addressed: 1) identifying students' perceptions of direction, persistence, continuing motivation, intensity, and performance in the context of teacher-directed goal setting, choice of instructional activities, and evaluation of performance; 2) identifying students' perceptions of the five personal investment behaviors in the context of portfolio assessment; and 3) comparing student perceptions as identified in problems one and two.
An Investigation of Selected Female Singing- and Speaking-Voice Characteristics Through Comparison of a Group of Pre-Menarcheal Girls to a Group of Post-Menarcheal Girls
The purpose of this study was to compare the speaking fundamental frequency, physiological vocal range, singing voice quality, and self-perceptions of the singing and speaking voice between two groups of girls ages 11 through 15 years, who were pre-menarcheal by 6 months and post-menarcheal by 10 months or more. Subjects were volunteers who attended a North Texas public school system. Each subject was examined by an otolaryngologist. Age, height, weight, a hearing screening, and information on music classes and/or private music lessons were obtained. The speaking fundamental frequency measure was obtained by having each subject speak for 30 seconds on a subject of choice and read a passage of approximately 100 syllables. The vocal range measure was obtained by having each subject begin at an arbitrary pitch and sing mah and moo up the scale as high as possible and mah and moo down the scale as low as possible. These four measures were repeated with the researcher giving visual gestures. For singing-voice quality, each subject sang "America" in the key of her choice and again in the key of F major. Each subjects singing voice was rated according to breathiness. Data regarding self-perceptions of the singing and speaking voice were obtained through a rating assessment of 10 questions and a conversation with each subject. There were no significant differences between the means of the pre-meanarcheal and post-menarcheal girls on speaking fundamental frequency, physiological vocal range, and singing-voice quality. But, more of the post-menarcheal girls exhibited lower speaking pitches, lower singing ranges, and increased breathiness in their singing voices than did the pre-menarcheal girls. Two questions of the perceptions rating assessment were significant, with the post-menarcheal girls citing higher incidences of vocal inconsistencies than the pre-menarcheal girls. The findings of the qualitative data analysis indicated that more post-menarcheal girls had ...
An Investigation of Selected Muscle Potential Activity in Violin/Viola Vibrato
The purpose was to investigate muscle potential during the vibrato motion for successful, healthy violin/viola performers. Electromyography was used to analyze parameters of muscle potentials during performance of a standardized exercise. These parameters were (a) evidence of potentials, (b) patterns of potentials, and (c) timing relationships (24 muscles). This study also sought to replicate and expand performance data from previous studies. Procedures from three pilot studies were used to standardize collection of EMG data. Synchronized video recordings were used to determine vibrato speed and conduct motion analysis. EMG data processing prior to analysis included power spectrum analysis and rectification, low-pass filtering, and smoothing data. Motion analysis findings (£D) were 1.09 for the elbow joints and 3.25 for the wrist joints. which was an indication of range of motion, suggested much greater activity in muscles controlling wrist movement than those moving the elbow. The degree of muscle potential and control were generally related to distance from the vibrating hand. Forearm muscle groups (8) demonstrated the greatest evidence of potential (76.5%) and were 18.1% non-periodic. Muscles of the upper arm (7) were off 59.4% and 57.0% non-periodic. Upper arm muscles had greater individual differences. Muscles of the chest and back (9) were collectively inactive (89.1%) and non-periodic (73.3%). With timing relationships, the forearm muscles demonstrated consistent firing patterns. Inconsistent firing patterns were evident in the upper arm, and to a greater degree in the chest and back muscles. Based on evaluations of performer motion and muscle potentials, it was strongly implied that there are (a) distinct roles for various muscles during vibrato (control vs. stabilization/support), (b) significant differences in potential between variables of rest, playing position, and performing, (c) significant differences in potential between some fingers, and (d) no significant differences between violinists and violists. The vibrato motion appeared to be controlled ...
An Investigation of the Influence of Evaluator Background on Appraisals of a Music Lesson Using the Texas Teacher Appraisal System
This study's purpose was to investigate the differences in scores and written comments given by two appraisal groups in their evaluation of a music teacher using the Texas Teacher Appraisal System (TTAS). One appraiser group had musical training while the other group specialized in other subjects. Analyses of both group's appraisal scores showed no significant differences. An examination of the written comments revealed that both appraisal groups focused on the same aspects of the lesson and used similar vocabulary. The TTAS instrument was a consistent measure of generic teacher behaviors in the music lesson, but it did not measure specific music teaching behaviors or encourage suggestions for improving musical instruction.
An Investigation of the Laryngeal Activity of Trumpet Players During the Performance of Selected Exercises
The study's purpose was to describe selected laryngeal activity of brass-wind players during the performance of selected musical exercises. Research problems included the observation and description of three internal areas of activity of ten trumpeters as they performed each exercise. Specific areas of observation were 1) movement of the epiglottis during the performance of each exercise, 2) movement of the vocal folds/arytenoid cartilage which includes changes in the size of the glottis during the performance of each prescribed exercise, and 3) movement of the thyroid cartilage during the performance of each prescribed exercise. Musical exercises performed by each of the subjects included a sound volume change, use of vibrato, single-tonguing, step-wise descending and ascending slurs, descending and ascending lip slurs, register change, and a descending chromatic scale. In addition, each subject performed an excerpt from the second movement of the Haydn Trumpet Concerto. Data were collected through direct observation of subject performances and then described using three different means. Data analyses revealed a prominent amount of highly individual, non-patterned laryngeal activity which played an integral role in the performance of each subject. Individuals including Law (1960), Cramer (1955), Jacobs (Stewart, 1987), and Noble (1964) have advocated an unrestricted airway during brass performance. Contrary to this advice, findings in the present study indicate that a great deal of varying, involuntary restriction is present in the laryngeal area during performance. Further, such activity appears necessary to brass performance. Others, including Farkas (1962), Schuller (1962), and Wick (1971) , have endorsed conscious use of the glottis during brass performance. While findings in the present study imply that there is a presence of voluntary or reflexive glottal activity during brass performance, evidence does not support any theory which suggests conscious use of the laryngeal mechanism.
An Investigation of the Needs for Music-Related Content in the Bible College Pastoral Curriculum as Perceived by a Selected Group of Pastors
The purpose of the study was to investigate the needs for music-related content in the Bible college pastoral curriculum as perceived by a selected group of pastors. The research problems were (1) to assess the extent of musical preparation of recent pastoral graduates from selected accredited Bible colleges in the United States, (2) to assess the music-related duties of those graduates in paid pastoral positions, (3) to assess the pastors' perceived needs for instructional preparation for the fulfillment of their musical duties, and (4) to determine the effect of selected factors on the perceived needs of those pastors.
