The effects of the ADDIE instructional design-based study model on the practice of pieces with aksak rhythm in orchestra studies

In this study, prepared as a doctoral thesis, the aim was to develop various studies, exercises, and works with aksak rhythms to be used in orchestra lessons and repertoires. Aksak rhythms refer to rhythms in 5, 7, or 9 beats that combine both duple and triple meters, differing from the usual patterns of 2, 3, 4, or 6 beats. In this study, certain works and exercises were prepared and applied to provide preliminary preparation for performing aksak rhythmic pieces in the orchestra. The study was designed based on the ADDIE instructional design model. Within the scope of the study, interview forms were prepared and discussions were conducted with orchestra members to identify the problems encountered in performing aksak rhythmic compositions during orchestra practice. Through these interviews, attempts were made to determine the current use of aksak rhythms in orchestras. Interviews with orchestra members were conducted to gather information on whether aksak rhythmic pieces are performed in orchestra repertoires, and if so, what challenges are experienced. In the continuation of the study, when working on irregularly metered pieces, preparatory exercises and various studies that could serve as preliminary work for the pieces were created and rehearsed with the orchestra. These exercises and studies were designed to provide prior preparation for potential problems that might be encountered. In the study, which was planned as a single-group pre-test and post-test design, the experimental group consisted of 14 orchestra members from Van Yüzüncü Yıl University (YYÜ) Academic Orchestra. This study aimed to introduce the characteristics of irregularly metered works, establish an appropriate practice discipline, draw attention to their musical properties and dynamism through increased use in orchestras, and contribute to the preparation of the pieces. The data obtained as a result of the study were analyzed, and the findings were written. Based on these findings, it was concluded that there were significant differences in favor of the post-test between the pre-test and the post-test at the end of the experimental process in which the scales and studies designed by the researcher were applied. In the final interviews conducted with the orchestra members, they also expressed positive opinions, stating that the conducted study was useful and applicable.
