Tap dance is a form of dance characterized by using ones shoes, as well as the floor, as a percussive instrument. As such, it is also commonly considered to be a musical form as well. Two major variations on tap dance exist, rhythm (Jazz) tap and Broadway tap. Broadway tap focuses more on the dance side, and is widely performed as a part of musical theater. Rhythm tap focuses instead on the musical side, and practitioners consider themselves to be a part of the Jazz tradition.
