About CYSO
The Claremont Symphony Orchestra Association founded CYSO in 1983 to provide an orchestral music experience for young people in Claremont and the surrounding cities. At the time, state-wide budget cuts were forcing schools to cut or reduce services, and programs in Music and Art were among the first to be negatively affected. The CSO Board conceived CYSO as both a supplement to school music programs and as a playing opportunity for students whose schools no longer offered orchestra classes.
CYSO is composed of approximately 50 students ranging in age from sixth through 12th grade. Current members represent 30 different schools (including home school) across 20 communities in the Los Angeles, San Bernardino, Riverside, and Orange Counties.
CYSO performs two free concerts annually in Bridges Hall of Music on the campus of Pomona College in Claremont, California. The orchestra is led by Music Director Robert Sage and managed by Executive Director David Van Brunt.
