Street theatre is a form of theatrical performance and presentation in outdoor public spaces without a specific paying audience. These spaces can be anywhere, including shopping centres, car parks, recreational reserves, college or university campus and street corners. They are especially seen in outdoor spaces where there are large numbers of people. Performers range from buskers to organised theatre companies, with the purpose of experimenting with performance spaces, promoting their mainstream work, or being commissioned for events such as street festivals, children's shows, or parades.
The logistics of doing street theatre necessitate simple costumes and props, and often there is little or no amplification of sound, with actors depending on their natural vocal and physical ability. This makes physical theatre, including dance, mime and slapstick, a very popular genre in an outdoor setting. The performances need to be highly visible, loud and simple to follow in order to attract a crowd.
