Popular swing dances include:
Lindy Hop -- Charleston -- East Coast Swing (aka: Triple step 6 count swing or single step Rockabilly swing)-- Balboa -- Collegiate Shag -- [Carolina Shag]? -- [Boogie Woogie]?-- and [St.Louis Shag]? (closely related to Charleston).
[Country Swing]? is yet another division of swing with a largely distinct culture. [WestCoast Swing]? is danced in the same environment as Country Swing and more widely know among the country swing dancers.
As with all swing dancing the lead and follow must have a connection.
