East Coast Swing (aka Triple-step Swing) East Coast Swing is mostly a 6-count dance. It rotates in a small stationary space on the dance floor. It can rotate either clockwise or counter-clockwise. It shares its history with West Coast Swing as a dance evolving from Lindy Hop. East Coast Swing can be further broken down into 3 categories: Single-Step Swing/Jitterbug, Double-Step Swing (Delayed Single-Step)/Retro Swing and Triple-Step Swing/East Coast Swing
History
Based on the Lindy Hop, East Coast Swing was created by dance studios in the 1940s due to market demand for training in Swing Dance. Various dance studios believed Lindy Hop was too difficult and too unstructured to teach to beginning dancers, thus East Coast Swing was developed as an alternative. It has also been called Eastern Swing, Jitterbug, American Swing, East Coast Lindy, Lindy (not to be confused with Lindy Hop), and Triple Swing. (Wikipedia).
