Abstract: Disclosed is a novel apparatus for the practice of use and simulation of a snare drum. The present invention provides a practice drumming pad that can reproduce the sound and feel of a snare drum, thereby allowing the user to practice proper rhythm and technique to produce the desired results when using a real snare drum. The practice pad of the present invention consists of a substrate having a rubber pad on the top surface, a recessed channel in the bottom surface, and a sound generating device consisting of a layer of pellets contained between two rigid plates secured in the recessed channel. The rigid plates and layer of pellets are secured in the recessed channel so as to allow little more than vibrational movement of the plates and pellets in the recessed channel. As one “drums” on the rubber pad, the vibrations are transferred to the plates and pellets to simulate the sound produced by a real snare drum.
