NMS’s Centennial year began in July 2011. Special events, performances, and celebrations took place during the year, including "High C," a grand celebration at Woolsey Hall at Yale University on June 10, 2012. The celebration featured premieres of two works commissioned by NMS: Ingram Marshall’s Eventide and Thomas C. Duffy’s Century Shouts. The decade ended with the launch of ATLAS, an independent middle school at NMS.
NMS is an anchor of the New Haven arts community and one of the ten largest community arts organizations in the country. Its integrative teaching philosophy allows for rich interactions among students of all ages, from toddlers to seniors nearing age 100. The diverse community thrives on informal jam sessions, multi-genre play-ins, dance concerts, workshops of all kinds, studio and schoolwide recitals, theatrical productions, and treasured "hallway conversations" between students, family members, faculty, and staff. At well over 100 years old, NMS continues to operate out of "an interest in serving a community, a neighborhood."
