What are different influences that go into tap dance?

Tap dance is a type of dance characterized by using the sounds of tap shoes striking the floor as a form of percussion. The sound is made by shoes that have a metal "tap" on the heel and toe. There are several major variations on tap dance including: flamenco, rhythm (jazz) tap, classical tap, Broadway tap, and post-modern tap. Broadway tap is rooted in English theatrical tradition and often focuses on formations, choreography and generally less complex rhythms; it is widely performed in musical theatre. Rhythm tap focuses on musicality, and practitioners consider themselves to be a part of the jazz tradition. Classical tap has a similarly long tradition which marries European "classical" music with American foot drumming with a wide variation in full-body expression. Post-modern or contemporary tap has emerged over the last three decades to incorporate abstract expression, thematic narrative and technology.
