The Dessoff Choirs is an independent chorus based in New York City. Margarete Dessoff established the organization in 1930 as the union of two choirs she directed, the Adesdi chorus and the A Cappella Singers, whence the plural Choirs. Today, the plural connotes Dessoff's various ensembles, which range from the large Dessoff Symphonic Choir, which appears with major orchestras, to the smaller Dessoff Chamber Choir, which performs in more intimate settings.
