A drummer is a percussionist who creates music using drums. Most contemporary Western bands that play rock, pop, jazz, or rhythm and blues include a drummer for purposes including timing and musical timbre embellishment. The drummer’s equipment includes a drum kit (or “drum set” or “trap set”) which includes various drums, cymbals, and an assortment of ancillary equipment such as pedals, standing support mechanisms, and drumsticks.

In particular, in the traditional music of many countries, drummers use individual drums of various sizes and designs, rather than drum kits. Some people only hit the drums with their hands.

In larger ensembles, the drummer may be part of a rhythm section that is played by other percussionists. These musicians provide the timing and rhythmic foundation that allows players of melodic instruments, including voices, to coordinate their musical performance.
