A circus is commonly a travelling company of performers that may include clowns, acrobats, trained animals, trapeze acts, musicians, hoopers, tightrope walkers, jugglers, unicyclists and other stunt-oriented artists. Circus music is any sort of music that is played to accompany a circus, and also music written that emulates its general style. The most common type of circus music is the circus march, or screamer, which is a march played at a very fast tempo. Popular music can also be arranged for the circus band, as well as waltzes, foxtrots and other dances.
