A drum kit (primarily American), drum set (primarily British/Australian), trap set, or just drums is a collection of drums and other percussion instruments, typically cymbals, which are set up on stands to be played by a single player with drumsticks held in both hands and the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. A drum kit consists of a mix of drums (categorized classically as membranophones, Hornbostel-Sachs high-level classification 2) and idiophones most significantly cymbals but also including the woodblock and cowbell (classified as Hornbostel-Sachs high-level classification 1). In the 2000s, some kits also include electronic instruments (Hornbostel-Sachs classification 53) and both hybrid and entirely electronic kits are used.
