Drums

A drum kit—also called a drum set, trap set, or simply 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).[2] In the 2000s, some kits also include electronic instruments (Hornbostel-Sachs classification 53) and both hybrid (mixing acoustic instruments and electronic drums) and entirely electronic kits are used.

A standard modern kit (for a right-handed player), as used in popular music and taught in music schools, contains:

A snare drum, mounted on a stand, placed between the player's knees and played with drum sticks (which may include rutes or brushes). A bass drum, played by a pedal operated by the right foot, which moves a felt-covered beater. One or more toms, played with sticks or brushes (usually three-floor tom, rack tom1/2). A hi-hat (two cymbals mounted on a stand), played with the sticks, opened and closed with left foot pedal (can also produce sound with the foot alone). One or more cymbals, mounted on stands, played with the sticks.
