This study explored factors relating to participation in public school orchestra programs and the relationship and predictability of such factors in accordance with Maehr's theory of personal investment.

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 …

Attrition rates among students in music teacher training programs have contributed to a shortage of qualified music teachers for the nation's schools. The purpose of this study was to investigate the predictive relationship of academic variables in three different learning environments and the intent of a select population of music education majors to leave the degree program. The study drew upon the work of Tinto, Bean and Astin to form a theoretical foundation for examining variables unique to student withdrawal from the music education degree plan. Variables were examined within the context of three different learning environments: (1) applied lessons, (2) ensembles and (3) non-performance courses. Participants were 95 freshmen and sophomore music education majors at a public university who were enrolled in the music education degree program during the spring semester, 2002. Data included participant responses on the Music Student Inventory (MSI), a questionnaire developed specifically for the study, and grade data from university records. Independent variables in the study included participants' perceptions of (1) Ensemble experiences, (2) Applied lesson experiences, (3) Non-performance music course experiences, (3) Course requirements, and (4) Performance growth. Additional variables included: (1) Ensemble placement, (2) Course grades for music theory, applied lessons and aural …

The purpose of this study was to determine the pitch and intensity level characteristics found in the vibrati of preferred oboe players whose vibrato was ranked by a panel of experts. The investigation also sought to discover factors that distinguish the preferred oboe vibrato from vibrato that is less preferred.

This study compared the effects from the use of aural and notated exercises as pedagogical procedures for teaching harmonic accuracy to beginning jazz improvisation students. The methods of pedagogy were identified from published pedagogic and historical sources, the results of oral and written traditions of jazz pedagogy. The performance objective was produced from a review of the related literature as a recognized and measurable characteristic of jazz improvisation. The purpose of this study was to compare measurements of harmonic accuracy, following the use of notated and aural exercises as experimental procedures of jazz improvisation pedagogy. A lesson plan, materials, curriculum and outline were developed followed by student recruitment and participation. A total of 20 student volunteers participated in the methods of pedagogy (aural or notation). Data collection consisted of a musical background questionnaire and pre and posttest performance recordings. Student recordings were evaluated by six judges using the “experimental performance evaluation measure.” Statistical analyses were conducted, including comparisons of pre to posttest effects between, and among the methods of pedagogy. Although all student participants performed mostly from notated music prior to this study, students who received the aural method of pedagogy produced greater improvement for all measurement items. While the …

The purpose of the meta-analysis was to address the varied and somewhat stratified study results within the area of singing ability and instruction by statistically summarizing the data of related studies. An analysis yielded a small overall mean effect size for instruction across 34 studies, 433 unique effects, and 5,497 participants ranging in age from 5- to 11-years old (g = 0.43). The largest overall study effect size across categorical variables included the effects of same and different discrimination techniques on mean score gains. The largest overall effect size across categorical moderator variables included research design: Pretest-posttest 1 group design. Overall mean effects by primary moderator variable ranged from trivial to moderate. Feedback yielded the largest effect regarding teaching condition, 8-year-old children yielded the largest effect regarding age, girls yielded the largest effect regarding gender, the Boardman assessment measure yielded the largest effect regarding measurement instrument, and song accuracy yielded the largest effect regarding measured task. Conclusions address implications for teaching, research pedagogy, and research practice within the field of music education.

The purpose of the study was to investigate the needs for music-related content in the Bible college pastoral curriculum as perceived by a selected group of pastors. The research problems were (1) to assess the extent of musical preparation of recent pastoral graduates from selected accredited Bible colleges in the United States, (2) to assess the music-related duties of those graduates in paid pastoral positions, (3) to assess the pastors' perceived needs for instructional preparation for the fulfillment of their musical duties, and (4) to determine the effect of selected factors on the perceived needs of those pastors.

The first purpose of this study was to describe collegiate band members' preferred teacher interpersonal behaviors and perceptions of self-efficacy based on the gender, year in college, instrument, and major. The second purpose of the study was to measure the relationship between preferences of interpersonal teacher behavior and self-efficacy scores. The non-probability purposive sample (N = 1020) was composed of band members representing 12 universities from different regions of the United States. There were 4 large public, 4 small public, and 4 private universities that participated in the study. Participants completed 2 questionnaires, the Teacher Interaction Preference Questionnaire (TIPQ) and the Self-Efficacy Questionnaire (SEQ). Descriptive statistics were calculated for each of the questionnaires. Results for the TIPQ showed that all sub-groups most preferred the dominant-cooperative behaviors, followed by submissive-cooperative behaviors, and least preferred the dominant-oppositional behaviors. Results for the SEQ showed subtle variations for all subgroups. Three Pearson product-moment correlation coefficients were calculated to measure the relationship between the three teacher interaction styles (dominant-cooperative, submissive-cooperative, dominant-oppositional) and students' perceived self-efficacy. Due to the possible over-use of the data with multiple correlations, a Bonferroni adjustment was made to avoid a Type I error (.05/3 = .016). A significant positive relationship was …

The purpose of this study was to determine the instructional methods of Oklahoma's elementary school music educators with respect to the inclusion of an authentic repertoire of American Indian music in the curriculum. The research was conducted through two methods. First, an analysis and review of adopted textbook series and pertinent supplemental resources on American Indian music was made. Second, a survey of K-6 grade elementary music specialists in Oklahoma during the 1997-1998 school year was conducted.

The reasons given by thirty-three junior high school band directors for success and failure at the University Interscholastic League Concert/Sightreading Contest were studied using the methodology of Attribution Theory. All of the subjects attended the same contest and were members of a region which included urban and suburban schools. The subjects responded to a questionnaire which evaluated their attitudes towards the contest, allowed them to make judgments about other directors in hypothetical contest situations, and finally asked them to list the five most important reasons for their success or failure at the contest in an open-response format.

The purpose of this study was to investigate the use of verbal communication and vocal performance during university-level applied studio voice lessons. Specific emphasis lay on the relationship between verbal communication, vocal performance, and instructional segments as defined by technical and song literature vocal repertoire.

The purpose was to investigate muscle potential during the vibrato motion for successful, healthy violin/viola performers. Electromyography was used to analyze parameters of muscle potentials during performance of a standardized exercise. These parameters were (a) evidence of potentials, (b) patterns of potentials, and (c) timing relationships (24 muscles). This study also sought to replicate and expand performance data from previous studies. Procedures from three pilot studies were used to standardize collection of EMG data. Synchronized video recordings were used to determine vibrato speed and conduct motion analysis. EMG data processing prior to analysis included power spectrum analysis and rectification, low-pass filtering, and smoothing data. Motion analysis findings (£D) were 1.09 for the elbow joints and 3.25 for the wrist joints. which was an indication of range of motion, suggested much greater activity in muscles controlling wrist movement than those moving the elbow. The degree of muscle potential and control were generally related to distance from the vibrating hand. Forearm muscle groups (8) demonstrated the greatest evidence of potential (76.5%) and were 18.1% non-periodic. Muscles of the upper arm (7) were off 59.4% and 57.0% non-periodic. Upper arm muscles had greater individual differences. Muscles of the chest and back (9) were …

This study investigated the effect familiarity with a teacher had on student interpretations of teacher verbal praise in seventh and eighth grade choral ensembles. A stimulus tape was constructed of 16, 30-second videotaped clips containing verbal praise of four teachers. Teachers identified their intent in the use of praise in each example. Students (n = 80) from the four choirs responded to the tape by labeling the praise in each clip as deserved or as one of three types of instructional praise (i.e., praise to encourage, to send a message to other students, or to seek student cooperation). Comparisons were made between choirs in labeling the praise. Comparisons were made also between each teacher's stated purpose in praising and the interpretations of choirs familiar and unfamiliar with the teacher. Choirs who were unfamiliar with the teacher differed from the teachers' own students in interpreting the praise: Students who knew a teacher labeled the praise as deserved in five clips, but unfamiliar choirs thought the praise served an instructional purpose. In four clips, choirs differed in their interpretations of the type of instructional praise. Students familiar with a teacher recognized their teacher's intent in praising in 12 of 16 clips. In …

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.

Hackman and Oldham's Job Characteristic Model was applied to study of perceptions community music school faculty hold towards their job. The research questions addressed core job characteristics of skill variety, task identity, task significance, autonomy, and feedback, critical psychological states (experienced meaningfulness, experienced responsibility, and knowledge of results); personal and work outcomes of satisfaction and motivation; need for professional growth. The results were compared to the national norms for nine different job families provided by Oldham, Hackman, and Stepina. Thirty-three schools, all members of the National Guild of Community Schools of the Arts, located in every geographical region of the United States, yielded 437 faculty responses (64% return rate). Of the core job characteristics, dealing with others and autonomy received the highest ratings; feedback and task significance received the lowest ratings. Of the psychological states, experienced responsibility yielded the highest rating and experienced meaningfulness yielded the lowest ratings. Of the personal/work outcomes, personal development and colleague relations received the highest ratings; pay satisfaction and overall general satisfaction received the lowest ratings. A comparison to the professional job family norms, using a one-sample ttest, found significant differences in 16 out of the 18 variables measured by the Job Characteristic Model. Strong …

The purpose of this study was to determine differences between the same subjects' music preferences at the elementary and high school levels, and the relationship between these findings and the following variables: peer preferences, musical training, excerpt familiarity, grade, gender, and race.

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.

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. …

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,

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 …

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 determine the physical elements which experienced trombonists associate with selected descriptors in characterizing the tone quality of that instrument. Stimuli sampled from live trombone tones and synthesized into musical phrases represented 17 variations in (1) presence/absence of attack transient, (2) rise time, (3) duration, (4) number of harmonics, (5) upper limit of harmonicity (6) spectral envelope shape, and (7) frequency.

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 …

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.
