Dance music is music composed, played, or both, specifically to accompany dancing.
It can be either the whole musical piece or part of a larger musical arrangement. Dance music works usually bear the name of the corresponding dance, e.g. waltzes, the tango, the bolero, the can-can, minuets, salsa, various kinds of jigs and the breakdown. Other dance forms include contradance, the merengue, the cha-cha-cha. Often it is difficult to know whether the name of the music came first or the name of the dance. Although dance is often accompanied by music, it can also be presented alone (Postmodern dance) or provide its own accompaniment (tap dance). Dance presented with music may or may not be performed in time to the music depending on the style of dance. Dance performed without music is said to be danced to its own rhythm.
