YOBC's Advanced Division is made up of four ensembles:
These ensembles are composed of some of the finest student musicians in Bucks County and surrounding areas. Most of their members perform with the Bucks County Music Educators Association festival orchestra. Many symphony members also participate in PMEA District, Regional and All-State ensembles; with the Governor's School for the Arts; and with community orchestras throughout the region. Students in our Advanced Division are eligible for our international tours and perform every other year in venues in New York City. Sophomores and juniors may take part in our annual concerto competition.
