The present disclosure provides a generation device having a plurality of operators that receive a user operation that causes generation of a sound. The generation device includes: at least one first operator arranged in a first region and configured to receive a first user operation that causes generation of a rhythm sound signal; at least one second operator arranged in a second region and configured to receive a second user operation that causes generation of a melody sound signal; and at least one third operator arranged in a third region and configured to receive a third user operation that causes a sound effect to be applied to a synthesized sound signal of the generated rhythm sound signal and the generated melody sound signal. The first region, the second region, and the third region are different regions of the generation device from each other.

A percussion surface apparatus includes: a head which is formed by rubber, and which includes a front surface and a back surface, the front surface which functions as a percussion surface; a cushion member which includes: a first layer that is butted against the back surface of the head, and that is formed by a fiber-based non-woven fabric; and a second layer that is adjacent to the first layer, and that is formed by a porous urethane material; and a supporting unit which is configured to fix and support the cushion member in a state where the cushion member is butted against the back surface of the head at a pressure.
