St. Louis shag is a swing dance that evolved from Charleston.[1] As its name suggests, it is recognized as being started in St. Louis, Missouri. It is a very fast closed position dance that is usually done to stomp, jump, and boogie-woogie music.
The dance may be done in the "side-by-side" Charleston position. The steps are: rock step, kick forward, step down, kick forward (other leg), stag, step, stomp (repeat).[2] The "stag" is bringing the leg up with the knee bent. As a variation, when repeating, one can do two forward kicks (or "switch, switch," referring to switching feet) in place of the rock step.
