The League of American Orchestras leads, encourages, and supports America’s orchestras while communicating the vitality and value of orchestras and the music they perform. The League strives to stimulate the exchange of ideas and practices, promote innovation, and foster 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 1,000 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.
