ACA is a nonprofit organization that publishes, distributes, and licenses music from its catalog. It is a service for composers to join the collective catalog, and promote their works to reach a wider audience, including international distributors of contemporary music and the general public. The ACA catalog is curated by professors and leaders in the field of classical music. We add over 100 new works every year. ACA does not require assignment of copyright by the composer, though certain aspects of copyright must be exclusively licensed to ACA in order for ACA to manage and administer services.
