Mission & Values

Conductor with Young Children - Orchestra

Founded in 1972, the InterSchool Orchestras of New York provides a comprehensive youth orchestra program that allows children to perform in an ensemble of their peers. Three graded orchestras lie at the heart of ISO’s programs, providing performance opportunities based on musical ability — not ability to pay tuition. More than 80% of our young musicians receive some degree of financial assistance.

ISO TestimonialsWe make it possible for students without prior access to an instrument or music lessons to get started on an instrument through loans of instruments and free music lessons.

We believe in the power of mentorship and the pursuit of excellence. Coaches rehearse and perform alongside our students in all ensembles. The six-to-one student-to-coach ratio is likely better than most students will experience in any other educational situation.

Our best students can become teachers to beginners through a teaching internship program. This develops the interns as teachers, provides them with meaningful community service, and helps educate the next generation of musicians.

ISO ensembles share their music with the community, performing at senior centers, churches, parks, and schools. It is particularly powerful when an ensemble of 6-to-10-year-olds performs for students of similar ages.

Playing music in an orchestra fosters a cooperative spirit, demonstrates that there is more than one valid interpretation of an idea, enhances students’ empathy for others, improves self-esteem, explores emotions, and makes students familiar with other cultures and periods of history. Whether students pursue careers in music or not, the ISO experience is something that makes a difference for their entire lives.

In October 2020 it was announced that ISO Ensembles would join the programs of Third Street Music School Settlement to create the largest and most expansive youth ensemble program in New York City. With a combined 175 years of experience in music education, this partnership galvanizes the missions of both organizations to ensure access to high-quality instruction for students from all five boroughs at a time when many music programs are closed because of the pandemic.


ISO was awarded the League of American Orchestra‘s 2004 Bank of America Award for Excellence in Orchestra Education, and was inducted into the Channel 13 Community Hall of Fame in 2006.


The InterSchool Orchestras of New York’s programs are made possible in part with public funds from the New York City Department of Cultural Affairs, in partnership with the City Council; the New York State Council on the Arts with the support of Governor Andrew Cuomo and the New York State Legislature; and many generous foundations and individuals.
