Gann's Music program offers a variety of musical exposure with academic courses and performance opportunities for both new and experienced instrumentalists, vocalists, composers, music lovers, and appreciators. Instructors work closely with students to foster their performance confidence, aesthetic perception, creative expression, responsible citizenship, and an awareness of the historical and cultural heritage of music through performance.

Performance ensembles include Jazz Band, House of Gann (chamber ensemble), Red Cleffers (choir), Grateful Dead (rock band), and ShenaniGanns (a cappella), all of which perform throughout the year.
