Real-world experiences, such as situated learning, fieldwork, and student teaching have been among the most prevalent examples employed in teacher preparation programs. Despite the increasing evidence in support of service learning in music teacher preparation, there are a limited number of models specific to instrumental music education. The purpose of this study was to explore the experiences of participants in one such model, called Band Project. Participants included preservice music educators, young band students, and one lead teacher who also served as the instrumental music teacher at the school. The research question that guided this investigation was as follows: In what ways do participants in an afterschool band project describe their experience? Four themes emerged from analysis of data: (a) Relationships and Community, (b) Challenges and Tensions, (c) Aspirations, and (d) Transformations. Findings reinforced the importance of service learning for preservice music educators, particularly amid growing concerns for cross-cultural awareness, inclusion, and social justice in music teacher preparation.
