A drum kit (or drum set or trap set) is a collection of drums, cymbals, and other percussion instruments that is used by a drummer in a musical group.

A normal drum kit consists of the following:

Other cymbals and drums can be added to the setup for a wider range of sounds like the Splash, a small cymbal around 10"/25 cm giving a distinct crash sound with a quick decay, or a China cymbal, that gives an "oriental feel" to beats, rhythms, solos and fills.  The latter is much like a crash cymbal popped inside out with the screw and sponge holding it to the stand inside it, so it has a shallow bowl shape.

The drummer can do other things to the kit, such as attach a tambourine to the spine of the hi-hat, so when he/she puts his/her foot down on the pedal or hits it with a drumstick, the drummer gets the tambourine sound at the same time.  Cymbals can also have rivets inserted into them to give them a 'sizzling' sound, or a cowbell can be attached to the top of the bass drum between the snare and floor tom to use in fills, solos, grooves, etc.
