Making Music: Composing "with" Young Musicians was a multi-year, multi-site research project partnered with the Ottawa-Carleton District School Board and the Canadian Music Centre to commission composers to collaborate with teachers and students to write educational music. On-site observations undertaken by the co-author and examined through a pragmatic lens employing Brief Focused Inquiry focused on the contributions of students, teachers and composers to the collaborative music compositions. Students contributed their creativity and knowledge of musical elements and concepts, and they provided feedback to the teachers and composers. Teachers contributed technical, instrumental feedback to the composers and their understanding of musical elements and concepts. Furthermore, they led band rehearsals and played musical instruments with the students. Composers contributed their musical creativity and feedback while undertaking a teacher-like role. The composers, teachers and students also used technology during this creative endeavor. The findings will be of potential interest to post-secondary music educators, composers, music teachers, and music publishers.
