Presented by Opera Theatre of Saint Louis, simply attend or join the chorus as part of a special event that brings professional OTSL main season artists together with hundreds of community volunteers from across the region to sing in harmony as one voice in our third “spontaneous” concert. Attendance is free. Participation is free and no audition is required. After registering, you will receive learning tracks to prepare for the rehearsal. Concert is “on book” so music does not need to be memorized. Head of Music Staff and Chorus Master Robert Ainsley leads both rehearsals and the performance.
