Tap dance is a form of dance characterized by using the sounds of tap shoes striking the floor as a form of percussion. Two major variations on tap dance exist: rhythm (jazz) tap and Broadway tap. Broadway tap focuses on dance; it is widely performed in musical theater. Rhythm tap focuses on musicality, and practitioners consider themselves to be a part of the jazz tradition.
The sound is made by shoes that have a metal “tap” on the heel and toe. There are different brands of shoes which sometimes differ in the way they sound.
“Soft-shoe” is a rhythm form of tap dancing that does not require special shoes, and though rhythm is generated by tapping of the feet, it also uses sliding of the feet (even sometimes using scattered sand on the stage to enhance the sound of sliding feet) more often than modern rhythm tap. It preceded what is currently considered to be modern tap, but has since declined in popularity.
