This study explored the responsibilities and experiences of three collegiate drum majors as student leaders of a marching band at a major university. Marching band continues to be a prevalent and highly visible aspect of music education in the United States. The preparation and utilization of student leaders in music remains common, but little research examining the actual experiences of student leaders in music has been conducted. As we continue to recruit student leaders for these positions, it may be of use to understand, from the student leader perspective, the challenges and perceived responsibilities associated with these positions. The participants in this study identified three distinct responsibilities of a drum major: (a) drum major as director's musical advocate; (b) drum major as director's political advocate; and (c) bridging the gap between students and staff. Additionally, the participants identified two concerns related to their experiences as student leaders in comparison to their band member peers: (a) social negotiations; and (b) defining an identity.
