West Coast Swing is a partner dance with roots in the Lindy Hop. It is characterized by an elastic look that results from its extension-compression technique of partner connection and is danced primarily in a slotted area on the dance floor. The dance allows for both partners to improvise steps while dancing together, putting West Coast Swing in a short list of dances that emphasize improvisation.[1]

Typically the follower walks into new patterns traveling forward on counts "1" and "2" of each basic pattern, rather than rocking back. Traditional figures include 6-count and 8-count patterns of one of the four basic varieties: (1) Starter Step, (2) Side Pass, (3) Push Break / Sugar Push, (4) Whip.[2]

Alternatively the basic patterns in West Coast Swing are defined as: Push Break (or Sugar Push); Left Side Pass; Right Side Pass; Tuck Turn; and Whip. Virtually all other moves in West Coast Swing are variations of these basic patterns.

The Anchor Step is a common ending pattern of many West Coast Swing figures.
