After-School Ensemble Program - Grades 7-12

GSJC Ensembles Program

GSJC ENSEMBLES – PROGRAM UPDATE

GSJC Ensembles won’t run for the 2026–27 school year, but our jazz education mission continues. Join our pre-registration list by November 30th to express interest in future camps and programs. We will consider opening up Semester 2 with enough student interest (minimum 60 total).

Build Real Jam Session Skills & Enhance Stage Confidence All Year

Professionally coached jazz ensembles help young musicians build confidence, improvisation, teamwork, and real performance experience. Jazz education is the vehicle to a more capable, connected, well-rounded musician.

Rehearsals, Coached Jam Sessions, & Summer Camp Credit

Put simply: students rehearse weekly in small jazz groups (called "combos") and learn jazz repertoire, improvisation skills, perform with peers and pros at local jam sessions, and earn credit toward summer camp!

How to Enroll

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

  1. Choose a plan above. Your first installment is charged at enrollment through our SessionUp platform.
  2. Complete the student profile, questionnaire, and agreements.
  3. 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.

  4. 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.

If we can’t arrange a suitable placement, you’ll receive a refund.

We use your student’s instrument, experience and availability to arrange their group. If we can’t offer a suitable combo or equivalent program, we’ll cancel the enrollment, stop future installments and refund your first payment in full within seven days after enrollment closes.

2026–27 Rehearsal & Jam Calendar
(Canceled until further notice)

What to Plan for Each Quarter:

Each quarter includes six weekly 90-minute rehearsals and two coached three-hour Sunday jam sessions. Rehearsals meet once-per-week, Monday through Friday after school, with Friday daytime options also available; each ensemble’s regular weekday and time is assigned based on placement and the availability families provide. Families receive their confirmed schedule before the quarter begins, and GSJC may adjust dates for major holidays, school performances, district festivals, or other cohort-wide conflicts.
