A single drum is a type of percussion instrument that consists of a cylindrical shell and a membrane stretched over one or both ends. It produces sound when the membrane is struck with a stick or hand. Single drums can vary in size and material, affecting their tone and pitch. Common examples include the snare drum and the bass drum. Single drums are widely used in various music genres, including rock, jazz, and classical music. They are often part of a larger ensemble, such as a drum kit or a marching band, providing rhythm and enhancing the overall sound of the performance.
