The Boston University School of Music Orchestral Program, which includes the Symphony Orchestra and the Chamber Orchestra, plays a central role in the education of the School's instrumentalists. The primary conductors, with faculty coaches and guest conductors, lead the orchestras in more than sixteen concerts each season including special performances such as two mainstage operas, the Student Concerto Competition Winners Concert, and two annual performances at Boston's Symphony Hall during which the Symphonic Chorus also appears. Readings and recordings of standard orchestral repertoire and student compositions take place throughout the year. The orchestras require placement auditions each September.
