The music department is housed in the Bixler Art and Music Center, whose facilities include a 394-seat recital hall, a large band-orchestra rehearsal room, a state-of-the art electronic music studio, classrooms, teaching studios, two more intimate seminar rooms, faculty offices, and practice rooms. Performances are scheduled in the recital hall, in the Page Commons Room, and in Lorimer Chapel. The music department shares the Bixler Building with the Art Department and with theĀ Colby College Museum of Art.

In addition to its collection of books, scores, and performing editions, the Art and Music library includes a listening center, a large collection of CDs, DVDS, and other recordings, a computer cluster, scanning and digital sound processing facilities, a seminar/study room, and resource materials for curricular and recreational needs. Colby is also home to the Ralph T. Gould Collection, a set of more than two dozen nineteenth-century brass and woodwind instruments.
