Now registering for the 2021-2022 Season!


Welcome to the 50th Anniversary of the Interschool Orchestras of New York! We invite you to become a member of one of the most prestigious and historic youth orchestras in the entire country. Alumni of ISO are members of some of the greatest orchestras in the world and you could follow in their footsteps.

Our 2020-2021 season was nothing like we’d imagined it would be, but we have managed to continue having our students make music, learn from world-renowned musicians, and for the first time ever we will present our one-of-a-kind collaboration with the Mingus Dynasty at the League of American Orchestras National Conference in June. This is the first time that ISO will be featured on the national stage and we couldn’t be more excited for the opportunity.

For 2021-2022, our 50th season, we will be celebrating the lives of the two people who shaped ISO into what it is today - our founder, Annabelle Prager, and our Music Director Emeritus, Jonathan Strasser. Many of our plans are still in motion, but we have some wonderful repertoire to play on numerous concerts planned for the year, including a year-end performance of Elgar’s Enigma Variations in its entirety. In addition to that, we are exploring opportunities for world premieres, exciting collaborations, major concert halls, the continuation of our groundbreaking mentor program, and an entirely new series of masterclasses. Of course, the plan is that we will be live and safely in person come September, which will be a long time coming for all of us.

Registration continues throughout the spring until sections are full. ISO’s goal is to make it possible for every interested young musician to be able to participate in an ensemble, regardless of ability to pay tuition. Financial aid is based on need, and half of our students receive some level of aid.  New families can apply for financial aid and our Student Services team is here to assist. We hope that you share our excitement for the 50th anniversary celebration and we look forward to seeing you soon!


Barry Stern
Musical Director, ISO at Third Programs


New York, September 29, 2020 – Third Street Music School Settlement today announces that InterSchool Orchestras of New York (ISO) will come under its umbrella to form 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.

Third Street will now offer a total of six orchestras for hundreds of students ages 8 to 18. This new orchestra program will offer generous financial assistance to students who otherwise would be unable to afford orchestral study and performance experiences.

“We are so pleased to welcome the ISO families, students and faculty to the Third Street community,” said Valerie G. Lewis, the Anna-Maria Kellen Executive Director. “Third Street and ISO were founded to connect young people to the music education they deserve and introduce them to the joys of group music making. During this challenging time, student ensembles play a critical role in helping children and teens avoid social isolation.”

The partnership will allow ISO’s orchestras to continue to flourish with the administrative and professional support of Third Street. The three additional orchestras will be called ISO at Third Street. The acquisition is expected to be completed by January. Third Street will immediately assume primary responsibility for the operation of the ISO program, with completion of ISO’s transfer expected to be completed following receipt of required government approvals later this year.

“We are so excited to affiliate with an enduring and respected organization like Third Street and benefit from its deep bench of artistic resources,” said Barbara Tracy, ISO Board President. “Our missions to reach disadvantaged students with the highest caliber of instruction are perfectly matched.”

In March when the pandemic forced public schools to close, Third Street and ISO quickly pivoted to virtual instruction for all programs and they continue online this fall. Third Street anticipates that in-person rehearsals will return slowly in the new year.

Arts education pioneer Emile Wagner founded Third Street in 1894 as the country’s first community music school. It has been guided by the dual goals of providing top-notch education and making sure disadvantaged communities and students of all ages and abilities have access to it. Third Street’s illustrious alums include songwriter, and EGOT winner Bobby Lopez, composer Jessie Montgomery and music director Ray Chew. The school’s ensembles have been showcased at many New York City venues, including Carnegie Hall, Symphony Space, Steinway Hall and Le Poisson Rouge.

Over five decades ISO’s youth orchestras have built a reputation for excellence. Founded by Annabelle Prager in 1972 because her son’s school didn’t offer ensemble music instruction, ISO attracts top students from all around the city. Its graded orchestras, led by experienced musicians with a passion for teaching, provide students a path to advance from beginner to virtuoso. The youth orchestras have delighted audiences in Carnegie Hall, Lincoln Center, Central Park and on tours of Europe and Latin America. ISO’s luminary alums include James Gaffigan, Chief Conductor, Lucerne Symphony, Switzerland and Tito Muñoz, Music Director, Opéra national de Lorraine & Orchestre symphonique et lyrique de Nancy, France.

All students are required to audition to determine skill level and placement into the appropriate orchestra. To schedule an audition, email Ivan Antonov at iantonov@thirdstreetmusicschool.org or call 212-777-3240.
