The Melbourne Shuffle (also known as Rocking or simply The Shuffle) is a rave and club dance that originated in the late 1980s in the underground rave music scene in Melbourne, Australia. The basic movements in the dance are a fast heel-and-toe action with a style suitable for various types of electronic music. Some variants incorporate arm movements.[1] People who dance the shuffle are often referred to as rockers, due in part to the popularity of shuffling to rock music in the early 1990s.
