A hi-hat, also spelled hihat, is a type of cymbal and stand used as a typical part of a drum kit by percussionists in rhythm and blues, hip-hop, disco, jazz, metal, rock and roll, house, reggae and other forms of contemporary popular music. It is a standard part of the modern drum kit. The hi-hat consists of two cymbals that are mounted on a stand, one on top of the other, and a pedal which can be used to clash and hold the cymbals together. Open and closed hi-hat refer to notes struck while the two cymbals are apart or together (open or closed), while pedal hi-hat refers to parts or notes played solely with the pedal used to strike the two cymbals. Most cymbal patterns consist of both open and closed notes.
