I am sure you know how this work. Special shoes are made for dancing the tap. What you do is that you use the sound of your shoe hitting the floor as a musical instrument. You can say that it is more like creating music with your feet and dancing to it at the same time. It is very interestingly, yet I figure it is really hard to learn. Rapid feet and leg movement is an absolute requirement. The roots of tap dance go deep into the African American dancing.
