Its main characteristic trait is its syncopated, or ragged, rhythm. It began as dance music in the red-light districts of American cities such as St. Louis and New Orleans years before being published as popular sheet music for piano. It was a modification of the march made popular by John Philip Sousa, with additional polyrhythms coming from African music.
