League of American Orchestras

The League of American Orchestras leads, supports, and champions America’s orchestras and the vitality of the music they perform. Its diverse membership of approximately 850 orchestras across North America runs the gamut from world-renowned symphonies to community groups, from summer festivals to student and youth ensembles. The only national organization dedicated solely to the orchestral experience, the League is a nexus of knowledge and innovation, advocacy, and leadership advancement for managers, musicians, volunteers, and boards.  Its conferences and events, award-winning Symphony magazine, website, and other publications inform music lovers around the world about orchestral activity and developments.  Founded in 1942 and chartered by Congress in 1962, the League links a national network of thousands of instrumentalists, conductors, managers and administrators, board members, volunteers, and business partners.
