MassACDA is the Massachusetts chapter of the American Choral Directors Association (ACDA). Founded in 1959, ACDA is a nonprofit music-education organization whose central purpose is to promote excellence in choral music through performance, composition, publication, research, and teaching. In addition, ACDA strives through arts advocacy to elevate choral music’s position in American society. ACDA membership consists of approximately 18,000 choral directors who represent more than one million singers across the United States. ACDA members teach choral music in public and private schools – kindergarten through senior high school – and at the college and university levels. They conduct a variety of choral groups, including boy choirs, children’s choirs, men’s and women’s choruses, junior and senior high school choirs, college and university choruses, ethnic choirs, vocal-jazz ensembles, and symphony choruses. They also conduct choirs in their communities and in their places of worship.
