The Embarquement Swing is a festival dedicated to Balboa and Lindy Hop dances.
Lindy Hop (or Lindy) is a partner dance that originated in 1920's and 30's Harlem, New York. The Dance itself consists of both 8 and 6 count steps and it includes footworks borrowed from Charleston and Tap. The dance can be wild and spontaneous, with frenzied kicks and body movements, or it can be cool and sophisticated. The most important aspects of it are that it is danced with your partner, to the music, and that you enjoy it!
Balboa is an 8 count dance so a connection with other 8 count dances would be consistent. It's hard to get a consensus view concerning the origins of Balboa. Many dance historians state that the dance was a derivation of Foxtrot, others believe it evolved from the Charleston or Collegiate Shag.
