Classes emphasize the development and strengthening of basic tap technique and terminology highlighting the importance of rhythm and sound. Tap focuses on rhythms and intricate footwork, creating a percussion instrument out of the dancer’s feet. Just like jazz vocalists who add rhythms to music by scatting, tappers add their voice by “scatting” with their feet. Rhythm tap tends to be a heavier or harder-hitting form of tap than Broadway tap, and sounds are made not only with the bottom of the shoe, but also with the back, sides, and tip. Rhythm tap is a broad category that encompasses the hoofing style.
