Treemonisha is an opera compose by the famed African-American ragtime composer Scott Joplin. Though it encompasses a wide range of musical styles other than ragtime, and Joplin himself never referred to it as such, it is still sometimes incorrectly referred to as a "ragtime opera". The music of Treemonisha includes an overture and prelude, along with various recitatives, choruses, small ensemble pieces, a ballet and a few arias .
