The League of American Orchestras leads, supports, and champions America’s orchestras and the vitality of the music they perform. The League works to stimulate the exchange of innovative ideas and practices and to promote unity across the orchestra field. The League delivers meaningful information, learning and leadership opportunities, grass-roots advocacy and other services to its diverse membership, which encompasses nearly 900 member symphony, chamber, youth, and collegiate orchestras of all sizes. Founded in 1942 and chartered by Congress in 1962, the League links a national network of thousands of instrumentalists, conductors, managers, board members, volunteers, staff members, and business partners.
