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 …

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.

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 …

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 …

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 …

The purpose of the study was to develop and evaluate a series of video-tape lessons to supplement the traditional lecture-discussion method of teaching a college course in advanced music theory. The specific problems investigated were: 1) to evaluate the effect of video-tape material on achievement in an advanced music theory course. 2) To assess the effect of the video-tape materials on the achievement in harmony, keyboard, sight singing, and ear training for students who had differential learning ability levels. 3) To assess the attitudes toward music theory and the use of the supplemental lessons. 4) To assess attitudes toward music theory and the use of the supplemental lessons and achievement for all students involved in the study. Analysis of co-variance, simple analysis of variance, t tests, and Pearson correlations produced statistical results that led to the following conclusions: 1) Students who used the video-tape supplemental lessons did not score higher on achievement tests in harmony, keyboard, sight singing, and ear training than the students who did not use those lessons. 2) Students who used the video-tape lessons had greater variance among the ability levels on the achievement tests; and for those using the lessons, students in the low beginning-ability level …

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.

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.

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 …

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 …

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 …

The purpose of this study is to provide a guide for the instruction of a trumpet mariachi performance ensemble in a music curriculum. The fulfillment of this purpose is dependent upon the data supplied in answer to the sub problems: (1) What socio-cultural information provides authentic trumpet mariachi music; (2) What trumpet mariachi literature illustrates the repertoire and style; (3) What instructional source materials may be developed such that Mexican American and non-Mexican American instructors build a competency in repertoire and style; (4) How could this guide be evaluated in its functional design for a music curriculum? The data collected for use in this study has been presented in three major categories: (1) the history and milieu in which the trumpet, mariachi crystalized; (2) the repertoire--its history and function in Mexican society and the transcriptions of types demonstrating the musical structure; and (3) the technical information relative to the instruction of the particular mariachi instruments. An evaluative instrument has been supplied in an attempt to establish the validity of the information and examples provided in this practicum. The validity of the research seems to rest on its authenticity and its serviceability. The findings of this study are stated as assertions …

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. …

Specific problems concerning the evaluation of the curriculum were, (a) to assess achievement in music theory fundamentals, (b) to assess achievement in jazz listening, (c) to assess improvement in jazz improvisation performance, (d) to assess student attitudes toward jazz improvisation and the curriculum. Based on the findings, the conclusions were as follows students benefited from the study of jazz improvisation, utilizing the developed curriculum, in the areas of, (1) knowledge of music fundamentals, namely, chord spelling, scale spelling and harmonic analysis; (2) identification of jazz tunes, composers, musical forms and prominent jazz performers; (3) improvisation performance in a jazz style, and (4) positive attitude toward improvement in jazz improvisation.

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 …

The purpose of this study was to survey and evaluate the music programs in Seventh-day Adventist academies in the United States during the 19 75-76 school year. Data were collected by means of a survey form sent to all principals and music teachers in the eighty schools and a music achievement test administered to graduating seniors in twenty-eight randomly selected academies. Although most departments judged the music facilities to be adequate, library materials such as scores, filmstrips, and in-service resources were needed in the majority of schools. One-half of the music programs did not have listening facilities available for classroom use. Comparing achievement test results for graduating seniors in Adventist schools with those of the standardization sample revealed no significant differences. The null hypothesis was rejected, however, when comparing size of school, location of school, type of school (boarding or day), sex of the student, and amount of piano and instrumental experience.

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 …

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.

The purpose of this study was to investigate the kinetic structures or reinforcement schedules of metric temporal patterns (metric combination of note values within a measure) in five best-selling beginning piano method series. Based upon a survey mailed to 98 music dealers, the five best-selling beginning piano method series in 1992 and 1993 were identified as: the Alfred Basic Piano Library, Bastien Piano Basics, David Carr Glover Piano Library, John. W. Schaum Piano Course, and John Thompson Modern Course for Piano. A coding system was developed for identifying the numerical appearances and occurrences of various metric temporal patterns per learning piece within each method series. Several computer programs were written to compute the kinetic structures, scope, and pacing of metric temporal patterns for each method series. The derived data were then compared to delineate relationships between the three analytical variables.

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 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 …

The purpose of this study was to develop and test systematically a theoretical model that delineated the constructs and subsumed variables of jazz improvisation performance. The specific research questions were; what specific performance variables are related to single line jazz solo improvisation performance? and; what is the most cogent groupings of variables into underlying constructs which characterize single line jazz solo improvisation performances for all performers, student performers, and professional performers?

The purpose of this study was to create and gain consensus of an essential curriculum for teaching score study in the undergraduate instrumental conducting class. Questions to be answered by this study were what methods, materials, and evaluations should be used to teach score study to undergraduate instrumental conducting students? Resolving the questions required the collection of information on the methods, materials, and evaluations used in teaching score preparation in the undergraduate instrumental conducting class and the opinions of conductors and teachers of conducting about those methods, materials, and evaluations.

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.
