Who We Are

Mainly Mozart Youth Orchestra is an inclusive youth orchestra serving children and their families all over the San Diego area. With six groups under the umbrella of MMYO we are able to include a large age range—all the way from 3 to 23. Students have the opportunity to play a variety of concerts in a range of venues, including the Balboa Theatre. World renowned musicians regularly visit to teach master classes and lead rehearsals. MMYO not only provides incredible performance opportunities and learning experiences, but also includes a high instructor-student ratio, coaching by and exposure to Mainly Mozart’s international Artist-Faculty, and inclusive programs for children with learning differences. Our mission is to enrich the lives of today’s and tomorrow’s passionate music lovers by connecting them to the genius and innovation of Mozart and the Masters, to world-class musicians and music-making, and to each other.

Associated Programs

Youth Orchestra of the Californias

The Youth Orchestra of the Californias is a collaborative effort of MMYO and the Centro de Artes Musicales in Tijuana, Mexico. It is America’s only binational youth orchestra. Students and conductors from MMYO and CAM join forces a few times a year to play a mixture of European and Latin American repertoire. Soloists from both countries join the orchestra, uniting the two nations through the universal language of music.

Chamber Music Institute

A 16-week course (ages 12–23) on Saturday afternoons at Mesa Community College beginning in January.
The program is led by the Hausmann Quartet and guest coaches hail from the roster of Mainly Mozart’s world renowned musicians. The Chamber Music Institute at the Mainly Mozart Youth Orchestra provides an environment where young musicians can come to realize their potential, hone their leadership skills and flourish while exploring the subtleties of ensemble playing through master classes, coaching and performance opportunities.

Unfortunately, limitations in staffing and space prevent CMI from happening this year.
