An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade

An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade

Date: May 1995
Creator: May, Brack M. (Brack Miles)
Description: 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.

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

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

Date: December 1986
Creator: Whitelegg, Clifford Paul
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.

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

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

Date: August 1989
Creator: Allen, Michael, 1954-
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 ...

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

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

Date: May 1986
Creator: Brown, Steven Franklin
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 ...

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

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

Date: May 1990
Creator: Williams, Bonnie Blu
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 ...

An Investigation of Selected Muscle Potential Activity in Violin/Viola Vibrato

An Investigation of Selected Muscle Potential Activity in Violin/Viola Vibrato

Date: August 1995
Creator: Weber, Matthew J. (Matthew Joseph)
Description: 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 ...

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

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

Date: December 1997
Creator: Bohnstengel, Carol
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.

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

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

Date: December 1989
Creator: Bailey, Robert E. (Robert Elwood), 1946-
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 ...
