Involving 28 grade eight students, this action research study examined strategies that lead to effective and efficient band rehearsals at the junior high level. Data was gathered concerning the proportion of instructional time spent on teaching concepts and skills, on active music making, and on classroom management. From this, and a review of the literature on best practice, new ways were designed to improved rehearsal practice. Data was then gathered to track their effectiveness and students' perceptions regarding the changes. (Contains 1 table and 1 figure.)
