A circus is commonly a travelling company of performers that may include acrobats, clowns, trained animals, trapeze acts, musicians, hoopers, tightrope walkers, jugglers, unicyclists and other stunt-oriented artists. The word also describes the performance that they give, which is usually a series of acts that are choreographed to music and introduced by a "ringmaster". The traditional circus is held in an oval or circular arena called a ring, which has tiered seating around its edge. In the case of traveling circuses this location is often a large tent which is nicknamed the "big top".
