Commonwealth Youthchoirs (CY) is a choral music education nonprofit transforming young lives through the power of making music together… one song at a time. Founded in 2001, CY empowers hundreds of children from across Philadelphia and the Greater Philadelphia region to find their voice and strive for excellence–in rehearsal, on the stage and as a member of the community in one of three programs: Keystone State Boychoir (KSB) , Pennsylvania Girlchoir (PG), and Find Your Instrument (FYI).
