There are two Wind Preparatory (Wind Prep) Ensembles that function as large symphonic bands, and mainly comprise middle school students, along with some high school students.
Under the direction of Artie Storch, the CYS Percussion Ensemble is a unique forum for talented musicians through grade 12. Members of the Ensemble study an exciting repertoire and perform in the Ensemble's 2-3 CYS concerts each year and at other music events around the Bay Area.
