Street jazz dance combines jazz dance, hip-hop dance and funk. Street jazz dance is a term used to describe dance styles that evolved outside dance studios in everyday spaces such as streets, dance parties, block parties, parks, school yards, raves and nightclubs. Often improvisational and social in nature, street jazz dance encourages the interaction and contact with other dancers and spectators from different countries. Street dance is also commonly used to identify the many hip hop and funk dance styles that began appearing in the United States in the 1970s and are still alive and evolving with hip hop culture today. These styles include breakdancing, popping and locking.
