Perception of Timbral Differences Among Bass Tubas

Description: The present study explored whether musicians could (1) differentiate among the timbres of bass tubas of a single design, but constructed of different materials, (2) determine differences within certain ranges and articulations, and (3) possess different perceptual abilities depending on previous experience in low brass performance. Findings indicated that (1) tubas made to the same specifications and constructed of the same material differed as much as those of made to the same specifications, constructed of different materials; 2) significant differences in perceptibility which occurred among tubas were inconsistent across ranges and articulations, and differed due to phrase type and the specific tuba on which the phrase was played; 3) low brass players did not differ from other auditors in their perception of timbral differences.

The Effect of Three Different Levels of Skill Training in Musical Timbre Discrimination on Alphabet Sound Discrimination in Pre-Kindergarten and Kindergarten Children

Description: 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 Free Play As an Instructional Tool on the Quality of Improvisation of First, Second, and Third Grade Children

Description: 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.

An Investigation of Perception of a Frequency Modulated Band Location of Pitch Within a Musical Vibrato

Description: 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 ...

Independent Piano Teachers: An Investigation of Their Attitudes toward Selected Attributes of Profession

Description: 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 ...

Selected Vocal Exercises and Their Relationship to Specific Laryngeal Conditions: a Description of Seven Case Studies

Description: Good vocal health is a vital concern for those people who use the voice in a professional capacity, such as teachers, singers, actors, clergymen, and lawyers. Research in the area of vocal health reveals the need to determine if specific exercises are beneficial to the voice and if exercises used to train the singing voice might be beneficial to alleviate pathological and/or dysfunctional voice disorders. The purpose of this study was to describe the response of a variety of pathological voices to a selected set of singing exercises. Subjects were selected from the private practice of cooperating physicians who felt that the vocal instruction and exercise program might be helpful to the teachers, students, professional "pop" singers, and housewife-singers who were diagnosed to have muscle tension dysphonia, nodules, recurrent laryngeal nerve paralysis, or iatrogenic dysphonia. Instrumentation for assessing conditions before, during, and after exercise included a brief case history, subject interviews, attending physicians' medical charts, flexible fiberoptic video nasolaryngoscopy, video cassette recorder and video tape segments, three physician/observers, and a specific diagnostic procedure which provided a method of assessing organic, functional, and perceptual variables. For the exercise program the researcher chose seven vocalises from the routine designed by Allan R. Lindquest, whose techniques combined those of the Italian school with those of Swedish studios which produced such singers as Flagstad and Bjoerling. The seven vocalises included a warm up "massage" and exercises for separation and blending of the registers, vowel clarity and modification, tone focus, vocal attack, and flexibility. Since all the subjects showed improvement after exercise in the vocal conditions observed in this study, these vocalises and technique may be helpful to alleviate pathological conditions and/or dysfunctional behavior in other subjects. The researcher further suggests that the voice profession investigate the efficiency of other techniques, exercises, and musical vocalises ...

A Spectral Analysis of Selected Vowels Sung by Bass and Baritone Student Singers

Description: While a limited body of research pertaining to vocal sound quality exists, technological advances in sound analyses have facilitated a reexamination of vocal timbre. The sound quality of sung vowels ([ a], [e ], C i ]) produced by ten baritone/bass singers at the University of North Texas was analyzed by the use of Fourier analysis and electronic digital equipment. This procedure and equipment produced results over a wider frequency range with greater accuracy than prior studies on vocal timbre. The study sought to answer the following questions: (1) Using formant regions between 0-20 kHz for comparison, what similarities and differences can be observed among spectra produced from [a], [e], and [ i ] vowels sung by baritone/bass singers? (2) Using formant regions between 0-20 kHz for comparison, what similarities and differences can be observed among spectra produced from [a], [ e ], and [ i ] vowels sung by baritone/bass singers with regard to individual singers? (3) Approximately what vocal-tract tube lengths were used by baritone/bass singers when performing [a], [e ], and [ i ] vowels? (4) What similarities in vocal-tract tube lengths can be generalized as to [ a], L e ], and [ i ] vowels sung by individual baritone/bass singers? The results of the study suggested that: (1) Below approximately 4 kHz formant frequency location can be generalized by a specific vowel between subjects. (2) Above 4 kHz the generalization of formant frequency location is difficult between subjects singing the same vowels, but general frequency location for formants can be identified between samples produced by the same singer performing different vowels. (3) Subjects did alter their vocal-tract lengths as different vowel sounds were performed, but no overall pattern of tube length with reference to specific vowels was indicated. (4) Each singer did use a unique ...

An Investigation of Conflicts in the Perceptions of Band Directors, School Administrators, and Selected Members of the Community About Their Respective Band Programs

Description: 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.

Relationships Between Selected Musical Aural Discrimination Skills and a Multivariate Measure of Intellectual Skills

Description: This study attempted to explore the strength and nature of relationships between specific intellectual information processing skills included in a multi-dimensional model conceived by Guilford, and measured by Meeker's Structure of Intellect - Learning Abilities Test, and specific musical aural discrimination skills as measured by Gordon's Musical Aptitude Profile. Three research questions were posed, which involved determining the strength and the nature of the relationship between MAP melodic, rhythmic, and aesthetic discrimination abilities and the intellectual information processing skills comprising the SOI - LA. Both instruments were administered to 387 fourth, fifth, and sixth graders from schools in the Dallas area. After a pilot study established the feasibility of the study and reliability estimates of the test instruments, multiple regression analysis determined that 10% to 15% of the variance between intellectual information-processing skills and the individual musical aural discrimination abilities was in common (r = +.32 to r = +.39). It was further determined that only six specific SOI intellectual dimensions, all involving the skills of "Cognition" and "Evaluation", were significantly related to the musical aural discrimination abilities. Through the use of the Coefficient of Partial Correlation, the strength of each individual information-processing skill's unique contribution to that covariance was determined. The study indicated that "Semantic" mental information processing skills, involving the ability to recall an abstract meaning or procedure given an external stimulus, play an extremely important part within this relationship. Skills of a "Figural" nature, which involve comprehending either a physical object or an non-physical idea and separating it from other impinging stimuli also enter into the relationship, although not to so high an extent. Finally, it was observed that the dimensions involving an understanding of "Systems", those mental skills which deal with groupings of figures, symbols, or semantic relationships, also was important to the relationship.

Improvisation in the Beginning Piano Class

Description: 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.

The General Music Course in the Secondary School: A Content Analysis of Selected Curricular Sources

Description: 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.

The Curricular Content of Elementary Music in China Between 1912 and 1982

Description: 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.

Music student teaching in Texas: A Delphi study of issues in the new millennium.

Description: The preparation of prospective music educators is a very complex undertaking that culminates with the student teaching practicum. However, the music student teaching experience may have less predictable expectations and results than the curriculum that precedes the event. The two-fold purpose of this study was (a) to investigate the music student teaching practicum in the State of Texas in an effort to establish current levels of success as perceived by the music educators involved in the process and (b) to identify any potentially problematic areas which might be in need of attention or revision. Thirty-six music educators (12 university supervisors, 12 cooperating teachers and 12 student teachers) who were recently involved in the music student teaching practicum in Texas were chosen as the sample in this two-round Delphi study. The first round Delphi survey, based on related literature, achieved consensus on 79% of the 108 item responses, and 15 of the 22 unresolved items reached consensus in round two of the Delphi process. The 34 sample members who completed the study ranked a final item in the second Delphi round concerning suggestions for the improvement of student teaching. The respondents showed a very high opinion of the music student teaching practicum. However, the cooperating teachers' responses were often lower, hence the recommendation that collaborative efforts between universities and public schools be strengthened. Recommendations for improvement were also made advocating: (a) adequate rehearsal time to be afforded the student teacher, (b) expectations to be clearly defined and articulated, (c) classroom management, measurement and media, and content area reading classes to be taught by music faculty, (d) videotaping to be used in the teacher-training and student teaching process, and (e) the length of the student teaching practicum to be extended. Five additional recommendations for improvement were made in areas deemed less urgent.

An Investigation of the Nonverbal Communication Behaviors and Role Perceptions of Pre-Service Band Teachers who Participated in Theatre Seminars

Description: This qualitative study used a multiple case study methodology to explore the nonverbal communication behaviors and role perceptions of pre-service band teachers, and the extent to which these individuals found meaning and value in theatre seminars with respect to those factors. The informants participated in three theatre seminars taught by theatre faculty at the researcher's university. The researcher collected data in the form of videotaped theatre seminar observations, videotaped classroom teaching observations, videotaped informant reflections of teaching episodes, online peer discussions and journaling, and informant interviews. Data were analyzed, coded, and summarized to form case summaries. A cross-case analysis was performed to identify emergent themes. The broad themes identified were past experience, adaptation, realization, and being aware. The informants found that the theatre seminars increased their awareness of nonverbal communication behaviors in the classroom, and had the potential to be meaningful and valuable with respect to their perceptions of their roles as teachers.

An Investigation of the Influence of Evaluator Background on Appraisals of a Music Lesson Using the Texas Teacher Appraisal System

Description: 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.

The Occupational Aspirations and Expectations of Students Majoring In Jazz Studies At The University Of North Texas

Description: The purpose of this study was to identify the occupational aspirations and expectations of students majoring in jazz studies, and to investigate relationships between students' aspirations, expectations and selected variables including significant others, choice of school, instrument type, academic achievement, academic level, socioeconomic status, age, gender, and early jazz experience. All jazz studies majors enrolled at the University of North Texas during the Spring 2001 academic semester responded to a pilot test questionnaire (return rate 85%, N = 211). Frequencies, percentages, means, and standard deviations described the students' occupational aspirations, occupational expectations, backgrounds and training in jazz prior to entering UNT, and determined the extent to which parents, relatives, teachers, friends, and role models helped steer them into jazz (Pearson r, Spearman Rho and Point Biserial correlation coefficients provided). The low to moderate positive correlation between aspirations and expectations (r = 0.43) indicated that the two variables were different and measured different types of occupations. Fifty percent of students aspired to be jazz performers whereas 29.7% expected to be jazz performers. While 42% aspired to be engaged in a combination of occupational activities, 48% expected a combination of occupational activities. Only 4.7% aspired to teach; however, almost 16% expected to be engaged in teaching. Low positive correlations were found between aspirations and significant others, expectations and significant others, expectations and gender, and expectations and role models. Respondents indicated that role models (jazz musicians, community musicians, and college instructors) had contributed the most to their decision to major in jazz. Recommendations for educators, researchers, and improvements to the questionnaire are provided.

High school string orchestra teacher as a career choice: A survey of 11th- and 12th-grade high school string orchestra students in Texas.

Description: 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 ...
