At Harvard College Opera, we pride ourselves in providing opera performance opportunities to undergraduates. Our casts have comprised many voice parts: sopranos, mezzo-sopranos, altos, contraltos, counters, tenors, and baritones. Our casts vary in size depending on the opera, but we typically search for approximately ten principals in addition to ten or more ensemble members.

Auditions for annual HCO productions take place during the last week of August or first week of September. Auditionees should prepare an aria or other operatic selection, and will be provided with an accompanist. Callbacks are held in the days immediately following Common Casting. More information about callbacks and cast lists will be given to you when you audition.

All students are welcome to audition, though it should be noted that, in keeping with our mission, priority will be given to Harvard undergraduates.

The staff of Harvard College Opera is entirely composed of Harvard undergraduates, and includes stage managers, set designers, costume designers, props designers, lighting designers, technical directors, rehearsal pianists, and more. Members of the staff have the opportunity to work alongside experienced technicians in the historic Agassiz Theatre and enjoy a high degree of artistic freedom. 

The staff of each opera is selected in March and April of the preceding year. If you are interested in joining the staff of a Harvard College Opera production, email us at


The orchestra of Harvard College Opera productions, like the cast and staff, is generally comprised of Harvard undergraduates, drawn from such ensembles as the Harvard-Radcliffe Orchestra, the Bach Society Orchestra, and the Brattle Street Chamber Players, and many more. Instrumentalists have the opportunity to play with a group of very talented and dedicated musicians, under the direction of our music director.

Auditions for the orchestra generally take place during the last week of September. Prospective orchestra members should prepare three minutes of a piece of their choosing. Around four rehearsals take place in the fall, followed by around four more rehearsal in late January. The four performances take place during the first week of February.
