West Coast Swing is a partner dance with roots in Lindy Hop, 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.

Partner dances are dances whose basic choreography involves coordinated dancing of two partners, as opposed to individuals dancing alone or individually in a non-coordinated manner, and as opposed to groups of people dancing simultaneously in a coordinated manner.
