Orchestra on Large Stage

Welcome to the InterSchool Orchestras of New York at Third Street

InterSchool Orchestras of New York (ISO at Third) provides three orchestras for students: beginning-intermediate orchestra, intermediate orchestra, and the advanced ISO Symphony. Admission to all groups is through auditions, which are held in the Spring.  September auditions will only be held for vacancies in the ensembles.

All groups rehearse weekly from early September through mid-May and give performances in concert halls and in community centers or schools. Instrumental coaches attend all rehearsals and play alongside their students offering assistance and support in all ensembles except the advanced ISO Symphony.

ISO graduates currently perform with leading orchestras across the country. Regardless of whether students pursue careers in music or not, the ISO at Third experience is something that makes a difference for their entire lives.
