How to Enroll
2026–27 enrollment is open and the first rehearsal window begins according to the schedule below.

You'll receive online materials to submit a playing sample, which will include a few scales, some basic note reading, and some open-ended performance instructions and questions. This is to help us place you in the best group fit for your student - it is not a prepared audition.
- Receive your instructor, rehearsal time, and location during the week before your first rehearsal. If your minimum-sized ensemble is not formed, you will be contacted regarding alternative options and solutions. More details are in the enrollment agreement - please review carefully.
