The music used in competitive dance routines is typically adapted from commercially available songs created by professional recording artists. Dance routines are subject to time limits at most dance competitions, and consequently the original, commercial music is usually edited to conform to such time limits
At some competitions, the dance competition music is adjudicated in terms of its appropriateness for the ages of the performers as well as the character of the dance routine. The quality of the music, however, is not explicitly judged. Even so, dance competition music is an integral part of a dancer’s performance, so dancers will sometimes employ professional music editing services in order to obtain high quality music—and thus a competitive edge—for their dance routines.
Dance routines may be performed without accompanying music. Although rare, this approach is most commonly employed in tap routines in order to feature the sound and rhythm of the dancer’s tap shoes.
