Carolina Shag is a six-count partner dance done mostly to moderate tempo music (100-150 bpm). During the dance the upper body and hips hardly move as the legs do convoluted kicks and fancy footwork. The lead is the center of attention, and the follow’s steps either mirror the lead’s or mark time while the lead shows off with spins and other gyrations. Carolina Shag is the state dance of North Carolina and South Carolina, and is still popular amongst residents of both states. (source:wikipedia)
