This is a research project based on the author’s experience of more than 20 years as conductor of the Eastern Cape Childrens Choir. It investigates the effectiveness of technical exercises - with special reference to selected “warm-up” exercises - in creating a superior choral tone in the children’s choir. The investigation is motivated by the fact that it is an ongoing challenge to effectively overcome problems with intonation and poor choral tone, problems which are mostly caused by lack of attention to pure vowel formation. Toward this end, a practical “tool box” of vocal exercises for the children’s choir is ultimately proposed. The toolbox is based on one single exercise with different variations. Each variation is designed to address multiple vocal needs and to correct vocal production during singing. In this manner a great many technical aspects are covered with the simplest of means and in the shortest possible time, bearing in mind that the rehearsal session allows limited time to focus on such matters to the exclusion of all else.

The purpose of this study was to analyze the characteristics of teacher directed modeling evidenced in the practices of three experienced high school choral directors. Research questions were: 1. What modeling activities were exhibited in each teacher's rehearsals? 2. When viewing a 45-minute composite tape of each teacher's instructional activities representative of all rehearsals, what instructional behaviors did each choral director recognize and identify as modeling? 3. What instructional episodes on the composite tape not identified by the teachers contained elements of modeling? 4. What other episodes from the remainder of each choral director's rehearsal practice contributed to an understanding of modeling? Videotapes of three high school choral directors were recorded over the course of one semester. Excerpts from rehearsals were combined to form a 45-minute composite tape of each choral director. A text transcription was made of the composite tape. Participant directors viewed their tape and identified instructional episodes that they recognized as examples of modeling. Identifications were analyzed, and descriptive categories of modeling behaviors were established. Modeling was found to be a teacher generated or delegated act of demonstration. Demonstrations were musical or non-musical and belonging to either of three distinct categories: audible, visible, or process modeling. Subdivisions of each category were found further describing modeling in the high school choral rehearsal. In addition, types of modeling were noted in increasing cognitive complexity required on the part of students beginning with simple imitation and concluding with models as tools for musical problem solving. Research is recommended on a larger sample of participants, including junior high/middle school directors to confirm categories and levels and to develop an observation tool based on results for describing, assessing, and modifying instructional techniques of practicing and pre-service music educators.

The purpose of this study was to examine the effects of three practice conditions on beginning band instrumentalists’ performance of a short musical selection. Fifty- nine sixth grade beginning band students were randomly assigned to either a physical practice, mental practice, or no practice (control) treatment. A pre-test score was obtained by having each subject sightread selection #2 from Form A of the Watkins/Farnum Performance Scale. Subjects were then given instructions according to the practice condition to which they had been assigned. After a three minute practice session, subjects were asked to perform selection #2 from Form B of the Watkins/Farnum Performance Scale to obtain a post-test score. All of the performances were tape recorded and scored on the basis of correct pitches and rhythm patterns by three music teachers. Mean scores were analyzed using a one-way ANCOVA and a Scheffe’ Test. The results of the study indicated that students in the physical practice condition scored significantly higher than those in the control group. Mental practice was not significantly different from either the physical practice or no practice (control) groups. / Master of Science

The trumpet ensemble has increasingly become a popular chamber ensemble inside music programs at the secondary and collegiate level. Chamber music ensembles are frequently guided by both democratic processes and ensemble coaches with limited chamber music experience. As trumpet ensembles grow in popularity, pedagogical resources are needed to guide rehearsals. This project serves as a guide for educators and performers to focus on fundamental issues related to trumpet ensembles as well as strategies for ensemble rehearsal.
