The Development of Occupational Identity in Undergraduate Music Education Majors

Description: The purpose of this study was to investigate the development of occupational identity in undergraduate music education majors using a Symbolic Interactionist theoretical framework. Three research problems were formulated: (1) The identification of occupational norms and values of undergraduate music education majors; (2) The determination of the commitment of under graduate music education majors to specific skills and knowledge of music education; (3) The determination of career commitment to music education by undergraduate majors. The sample consisted of undergraduate music education majors enrolled in North Texas State University; Denton, Texas, during 1981 and 1982. A questionnaire and interview schedule, which had been developed in a pilot study, were used to gather data. Questionnaire responses from 165 students were analyzed by comparing selected variables by area and by class year. These data were further clarified by information from thirty-eight interviews conducted by this researcher.

Effects of an Auditor's Past Musical Experience on the Intelligibility of Vowel Sounds in Singing

Description: The purpose of this study was to determine the effects of an auditor's past musical training and experience on the intelligibility of selected vowel sounds at differential pitch levels. The specific problems of the study were to investigate the effects of extensive vocal music training, extensive non-vocal music training, and limited or no music training on an auditor's ability to discriminate accurately selected vowel sounds performed at various pitch levels. The effects of pitch and vowel sound on auditor recognition of vowel sounds in singing and the ability of each singer to be intelligible to auditors was also investigated.

An Investigation of the Relationship of Self Concept to Selected Communication Skills of Choral Conductors

Description: This study investigated the relationship between selected measures of self concept as perceived by a group of choral conductors, their eye dependency on score, and the measures of expressive voice. The problems were (1) to determine the degree of perceived self concept of a selected group of choral music teachers through measures of (a) total self, (b) physical self, (c) moral-ethical self, (d) personal self, (e) family self, and (f) social self? (2) to assess eye dependency on score of the same teachers; (3) to assess the aspect of expressive voice through measures of (a) pitch levels of modulation, (b) speech flow, and (c) voice energy level; and (4) to examine the relationship between the measures of self concept, eye dependency on score and expressive voice.

A Comparison of the Acoustical Properties in Solo and Ensemble Performance of the Trombone

Description: The specific problems investigated involved identifying and describing the characteristics of fundamental frequency, overall intensity, and spectral content in unaccompanied and ensemble performance settings. Additionally, comparisons and descriptions of the relationships among these acoustical parameters were made. Fifteen trombonists were used as research subjects. Each subject recorded a selected musical excerpt in the following performance modes: high register unaccompanied, harmonic, and unison ensemble; and low register unaccompanied and unison ensemble. Tape recordings of these subjects were used in conjunction with certain electronic apparatus to obtain data on frequency, intensity, and spectral content. Based on these data, descriptions of these acoustical parameters and comparisons of unaccompanied and ensemble performance settings were made.

The Effect of Rhythm on Melodic Expectancy

Description: The present study sought to confirm melodic expectancy patterns discovered in a previous investigation and to determine whether data would be affected by altering the rhythmic condition of the stimuli. The three problems of this investigation were to study expectancies generated by two-note stimulus intervals of equal duration; the expectancies generated by stimulus intervals presented with a long-short rhythm; and the expectancies generated by stimulus intervals presented with a short-long rhythm. Fifty subjects were asked to sing what they believed would be the natural continuation of the melody begun by a two-note stimulus interval. The stimulus intervals were grouped in rhythmic sets, one set of neutral-rhythm stimuli, one set of long-short stimuli, and one set of short-long stimuli. The interval from the second note of the stimulus interval to the first sung note was transcribed as the generated expectancy response interval. The data were examined in two basic ways, using response data as a whole and examining data for each stimulus interval separately. A third method of data evaluation concerned harmonic triads occurring in the response data. Both when considering response frequency as a whole, and when considering response data separately for each melodic beginning, no significant difference associated with rhythmic condition could be found. Smaller response intervals were generated much more often than large intervals. Some stimulus intervals, notably the major second ascending, were observed to be much more powerful generators than others. It was concluded from these results that in response to two-note stimulus intervals melodic expectancy can clearly be shown to operate, confirming the results of an earlier study, but that no effect of rhythm on melodic expectancy can be shown to operate.

An Investigation of the Career Realities and Occupational Concerns of Selected Professional Performing Musicians

Description: The purpose was to investigate the career realities and occupational concerns of successful full-time performing instrumentalists. Four research problems were formulated; (1) the establishment of a demographic profile of musicians who perceived themselves successful; (2) the determination of the musicians' career realities; (3) the determination of the musicians' occupational concerns; and (4) a comparison of the relationship of the demographic profile to the career realities and occupational concerns. A pilot study was used to develop a questionnaire and an interview schedule. The sample for the main study was chosen by the questionnaire and consisted of twenty musicians, five each in the musical categories of jazz, classical, commercial and pop. To resolve research problem one, the questionnaire also collected general demographic data. Research problems two and three were fulfilled by an interview schedule based upon career realities and occupational concerns cited in previous sociological studies. The realities and concerns were either confirmed or refuted by each interviewee. The career realities were role conflict, career contingencies, musical labels, life style, hierarchies, audience relationships and environment. The occupational concerns were mobility, status, entrapment, personal contacts, dependency, security, competition, economic issues, working conditions, travel requirements, appearance, management control, auditions, maintenance of skills and training relevancy. The interviews were taped and transcribed by a court reporter and included in the text. An analysis of the interviews in relation to the demographic data fulfilled research problem four. Results showed that career contingencies, mobility and life style were positive influences for the sampled musicians. Also, a "hierarchy of expertise" appeared as the ultimate occupational hierarchy for the sampled musicians. Furthermore, a "hierarchy of dependency," based upon instrument played, affected the sampled musicians' attitudes toward their careers. It was concluded that performers who were devoting their full time to performance were more tolerant of imperfect career conditions than ...

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 ...

An Investigation of the Whistle Register in the Female Voice

Description: The purpose of the study was concerned with specific elements of the portion of the female voice commonly referred to as whistle or flute register. Three elements of vocal production were chosen for which past research has demonstrated relationships to source function. These elements included spectral characteristics, airflow rates, and perceptual identification. The research compared what the singer-subjects perceived as being whistle register phonations with that which they perceived as being head register phonations. A comparative technique was utilized where pitch, intensity and phonemic category were held relatively constant, register, therefore, being the only variable. Spectral characteristics and airflow rates of the two subject-determined registers were compared. In addition, an attempt was made to determine if the whistle register could be perceptually differentiated on the basis of voice quality,

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.

Aesthetic Justifications for Music Education: a Theoretical Examination of Their Usefulness

Description: 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 ...

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 ...

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

Description: 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.

An Investigation of Holland's Theory of Vocational Personalities and Work Environments As Applied to Undergraduate Music Majors

Description: 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 ...

The Texas Music Educators Association: A Historical Study of Selected Landmark Events Between 1938 and 1980 and the Decisions Which Influenced Their Outcomes

Description: The purpose of this study was to investigate selected landmark events in the historical development of the Texas Music Educators Association, 1938-1980, and the decisions which influenced their outcomes. A polling of twenty former presidents of TMEA selected the following landmark events that helped to shape the history of TMEA: (1) the change from a band organization to a music educators organization in 1938, (2) the University Interscholastic League takeover of contests in 1947, and (3) TMEA's separation from the Music Educators National Conference in 1976. In addition to developing a historical chronology from documentary sources, in-depth interviews were conducted with actual participants in these landmark events. The interviews utilized comparable questions, in order to identify decision-making patterns, while also capturing the atmosphere and visceral context of TMEA history. Literature from the social science disciplines on organizational decision—making was explored for help in understanding what happened, how, and why. In all three events the final decision was strongly influenced by factors external to the TMEA. The strong power position held by school administrators was evident in both the first and second events, while reinforcement from actively lobbying choral directors was also a factor in the first event only. The strong ultimatum from MENC, backed by their unchallenged charter authority, was a key factor in the third event. Still, TMEA continued to grow, and avoided debilitating organizational trauma. TMEA leaders often demonstrated a capacity to react quickly to sudden changes in the organizational environment, turning potential liabilities into assets. The TMEA was found to be an organization greatly dependent on the decisions of others, but strongly independent and self-sufficient in spirit. This independence has both negative and positive potential. It can become an unnatural barrier between Texas music educators and the MENC, or it can fuel the drive for professional excellence ...

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.

An Investigation of the Laryngeal Activity of Trumpet Players During the Performance of Selected Exercises

Description: 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 Selected Female Singing- and Speaking-Voice Characteristics Through Comparison of a Group of Pre-Menarcheal Girls to a Group of Post-Menarcheal Girls

Description: 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 ...

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 ...
