Circus artists develop original performance pieces showcasing great artistic and performing skills, emotive depth and artistic proposals for the general public. Alone, or collectively, they may perform one or more traditional or original circus disciplines, which are usually based on physical capabilities such as strength, balance, agility, flexibility, ability and coordination of body parts, and combined with performance disciplines such as dance, theatre, mime etc. The physical nature of the exercises performed often includes a certain level of risk for the performer.
