This study's purpose was to investigate the phenomenon of hemispheric specialization for the pitch and rhythmic aspects of melody. Its research problems were to investigate the Influence of pitch, rhythm, and training on hemispheric specialization for pitch-plus-rhythm melodic fragments. A final problem was to examine the relationship between dlchotic ear scores and eye movements evidenced during melodic processing. Twenty musicians and twenty nonmuslcians, right-handed and equally divided as to gender, participated in the project. Accepted dlchotic testing and eye behavior indexing procedures were implemented to investigate each research problem. The dlchotic tape produced for the study contained five subtests In which pitch activity was variously greater than, less than, or equal to rhythmic activity.

The purpose of this study was to investigate the frequency modulations and the intensity modulations of the hand vibrato and the jaw vibrato as they relate to performance on selected brass instruments. Ten trumpet players and ten trombone players were recorded performing a musical exercise which was written in three different registers. Five performers in each group used a hand vibrato and five used a jaw vibrato.

This study's purpose was to investigate the kinds of instructions provided for teachers by authors and publishers of elementary music series for the development of children's voices. Specifically, the study was 1. to investigate the recommended methodology related to the development of vocal concepts in children, 2. to investigate musical aspects that could be indicators of expected vocal ability in children, and 3. to relate the findings of this study to other research results that give insight into the vocal capabilities of children. To collect the data, the teacher's editions of grades one, three, and five of music series published by the Silver Burdett Company and by the American Book Company during the period circa 1945 to 1975 were subjected to a content analysis and to a musical analysis. Three categories were established for the content analysis: Vocal Characteristics, Singing Objectives, and Teaching Strategies. Validity of the research tool was tested by the jury method and by logical validity. Reliability coefficients of .90 were determined by using two additional coders and by re-coding material.

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.

The purpose of this study was to ascertain what competencies professional accompanists and accompanying teachers deem sufficiently important to be included at some point in the development of a professional accompanist. Research problems were formulated to determine what differences exist between opinions of teachers and professionals regarding necessary skills in preparation of accompanists in (1) pianistic skills, (2) accompanying skills, (3) vocal skills, (4) linguistic skills, (5) knowledge of repertoire, (6) understandings in human relationships, and (7) other competencies. Data were collected by means of a validated questionnaire containing items grouped into the seven categories listed above. It was sent to twenty professional accompanists and thirty-one schools offering accompanying degrees. Seventy per cent of the professionals and 84 per cent of the schools responded. Each competency was rated first for its relative importance to a professional accompanist and then for its appropriate place in the sequence of an accompanist's preparation. A chi square comparison of responses of the two groups regarding the importance of each competency showed virtually no significant differences. Responses on appropriate stages of training were not treated statistically.

This study's purpose was to examine and compare pedagogical opinions and suggestions regarding teaching American art-songs recommended as suitable for beginning voice students. Specific problems were to determine 1. The ten American art-songs most recommended by voice teachers for beginning students, 2. Pedagogical opinions and suggestions about these art-songs, 3. Voice teachers' general opinions and suggestions regarding teaching American artsong, 4. Ways in which their opinions and suggestions were similar and 5. Ways in which their opinions and suggestions were dissimiliar.

The present study explored whether (a) positive or negative reinforcement would produce higher percentages of on-task student behavior at set timed intervals, (b) positive, negative, or total reinforcement would increase student attentiveness after reinforcement, and (c) if natural fluctuations in teacher approval/disapproval would have any bearing on percentages of student attentiveness. Findings of the 15-day study concluded that (a) positive reinforcement maintained significantly higher levels of student attentiveness over negative reinforcement, (b) negative reinforcement did not significantly lower percentages of student attentiveness, and (c) natural fluctuations in rates of teacher approval/disapproval had no apparent effect on the amount of on-task behavior in the beginning strings class.

The purpose of the study was to design and evaluate materials for integrating musical concepts and stylistic concepts into the high school choral rehearsal. Need for the study was established by examining related literature and by means of a survey of Texas high school choral directors. A systems approach model of curriculum development, consisting of a ten-step procedural outline, was adopted for formulation of the study. The following criteria for the curriculum, called Integrated Musical Information for Choirs (IMIC), were set: (1) Materials should be in the hands of each student; (2) Materials would relate directly to music being performed by the choir; (3) Use of the materials should assist the teacher in organizing his/her work; (4) Teachers should be able to put materials into use without adaptation; (5) Teachers' out-of-class preparation should be minimal.
