Applying the principles of critical editing to a variety of American idioms, including jazz, psalmody, popular song, twentieth-century chamber music, art song, Native American ceremony, and the Broadway show, MUSA is devoted to expanding the legacy of American music available for study and performance. MUSA (pronounced "mew-za") is publishing a forty-volume series of scholarly editions of American music. In addition to musical notation, each volume includes a substantial essay and a critical editorial apparatus. By bringing notated music and scholarly interpretation together in the same volume, each MUSA volume seeks to place the sounds of music making in the United States within the context of the nation's cultural life.
MUSA was founded in 1988 as a collaborative venture administered by the American Musicological Society through its Committee on the Publication of American Music (COPAM), and is published by A-R Editions. The Society for American Music contributes to the development of the series through its representative to COPAM. MUSA is supported by a grant from the National Endowment for the Humanities and hosted by the University of Michigan at its American Music Institute.
