Here’s a little video showing the basics of Salsa. The back-and-forth basic (basic A) is the staple basic move of many styles of salsa, including L.A. style and N.Y. style. It is characterized by direct movement, and works well in small spaces. Basic B, or the back basic (sometimes referred to by ballroom dancers as the 5th position break) is indicitave of many South American and Carribbean native styles of salsa. This one, although not demonstrated this way in the video, can move in a very flexible way, and is also associated with similar dances, like Cumbia.
