Mass (Bernstein)

MASS (formally, "MASS: A Theatre Piece for Singers, Players, and Dancers") is a musical theatre work composed by Leonard Bernstein with text by Bernstein and additional text and lyrics by Stephen Schwartz. Commissioned by Jacqueline Kennedy, it premiered on September 8, 1971, conducted by Maurice Peress. The performance was part of the opening of the John F. Kennedy Center for the Performing Arts in Washington, D.C.Mass premiered in Europe in 1973, with John Mauceri conducting the Yale Symphony Orchestra in Vienna.

Originally, Bernstein had intended to compose a traditional Mass, but instead decided on a more innovative form. The work is based on the Tridentine Mass of the Roman Catholic Church. Although the liturgical passages are sung in Latin, Mass also includes additional texts in English written by Bernstein, Broadway composer Stephen Schwartz, and Paul Simon (who wrote the first quatrain of the trope "Half of the People"). The work is intended to be staged theatrically, but it has also been performed in a standard concert setting.

Initial critical reception, including a review in the New York Times, was largely negative, but the Columbia Records recording of the work enjoyed excellent sales.

The original cast consisted of a Celebrant, three choirs, and altar servers. A full classical orchestra performed in the pit, while onstage musicians—including a rock band and a marching band—performed and interacted onstage.
