The Salsa is a lively, fiery and enjoyable dance that is really easy to get the basics of. In essence, Salsa is no more than a step forward and a step back, with a rock in between. It's largely a partner dance, but with many fancy "shines" that can be thrown in individually.
Traditionally in Salsa Dance the Man is the Leader and the Woman is the Follower. Together the Leader and the Follower are known as Dance Partners or simply Partners. The Man guides the woman by giving her "claves", These "claves" are little tugs, pushes, or checks given at the right time in the momentum of the dance that let the Follower know when to turn, hesitate, dip, cross-body, etc.
As a single man or woman - social dance is as close to a magic pill as has ever been created or dreamt of. You'll meet endless people, and never again be lonely, or unable to meet people at your slightest whim.
