East Coast Swing: Often called by other names such as the Jitterbug and the Bop, there are many different versions of East Coast Swing. The rock step creates a spring action between the partners in opposition to each other on count "1" and the dance rotates circularly. The version taught most often here is 6-count triple rhythm East Coast Swing. It is one of the easiest to learn of all the swing styles, and versatile enough to dance to most tempos of music. Other versions include single-rhythm swing, double-rhythm swing, 8-count Lindy, Lindy Hop, Flying Lindy, and Hollywood-style Lindy.
