Abstract
A dancing tap comprising three elements arranged in such a way as to require no external apparatus for assembly. There is recited a first plate-like body having a central through bore and multiple recesses on its first and second faces, a second plate-like body received by the central through bore of the first plate-like body and containing multiple protrusions, a sound spring equipped with a dimple that mates with a protrusion on the second face of the second plate-like body. The protrusion of the second plate-like body hitting the periphery of the dimple on the sound spring produces a novel tapping sound.
