South Korea MM Street Dance Competition

Street dance, more formally known as vernacular dance,^[1] is an umbrella term used to describe dance styles that evolved outside of dance studios in any available open space such as streets, parks, school yards, raves, and nightclubs. They are often improvisational and social in nature encouraging interaction and contact with spectators and the other dancers. These dances generally evolve out of urban and suburban spaces in some form of underground culture or region; they are a part of the vernacular culture of that geographical area (as if they were folk dances; although since the advent of the internet, the dances seem to be shared amongst people with the same musical interest worldwide). Therefore, street dance refers to modern folk dance with the term 'street' being more accurate since much of the modern world is now urbanized and because in more modern times there is not so much a barrier between the high society and everyday folk. Some examples of street dance include B-boying, more commonly known as breakdancing, which originated in New York City,^[2] Melbourne Shuffle which originated in Melbourne, Australia^[3] and Tecktonik which originated in Paris, France.^[4] The term street dancer usually refers to someone that congregates various street dances for appliance as a competitive form. Vernacular dance is a more formal term, but street dance is a more popular term since most of these dances evolved in urban and suburban areas (i.e. towns, cities, etc).
