Community theatre refers to theatrical performance made in relation to particular communities—its usage includes theatre made by, with, and for a community. It may refer to theatre that is made entirely by a community with no outside help, or to a collaboration between community members and professional theatre artists, or to performance made entirely by professionals that is addressed to a particular community. Community theatres range in size from small groups led by single individuals that perform in borrowed spaces to large permanent companies with well-equipped facilities of their own. Many community theatres are successful, non-profit businesses with a large active membership and, often, a full-time professional staff. Community theatre is often devised and may draw on popular theatrical forms, such as carnival, circus, and parades, as well as performance modes from commercial theatre. Community theatre is understood to contribute to the social capital of a community, insofar as it develops the skills, community spirit, and artistic sensibilities of those who participate, whether as producers or audience-members.
