Salsa’s roots are based on Cuban Son, specifically to the beat of Son Montuno in the 1920s. However, as it is a popular music, it is open to improvisation and thus it is continuously evolving. New modern salsa styles are associated and named to the original geographic areas that developed them. There are often devotees of each of these styles outside of their home territory. Characteristics that may identify a style include: timing, basic steps, foot patterns, body rolls and movements, turns and figures, attitude, dance influences and the way that partners hold each other. The point in a musical bar music where a slightly larger step is taken (the break step) and the direction the step moves can often be used to identify a style.
Incorporating other dance styling techniques into salsa dancing has become very common, for both men and women: shimmies, leg work, arm work, body movement, spins, body isolations, shoulder shimmies, rolls, even hand styling, acrobatics and lifts.
Latin American styles originate from Cuba and surrounding Caribbean islands including Puerto Rico, and the Dominican Republic and then expanding to Mexico, Venezuela, Colombia, and the rest of Latin America; also heavily influence “Miami” style which is a fusion of Cuban style and North American version. The styles include “Casino”, Miami-Style, Cali-style and Venezuelan Style.
North American styles have different characteristics: Los Angeles style breaks on the first beat “On 1” while New York style breaks on the second beat “On 2”. Both have different origins and evolutionary path, as the New York Salsa is heavily influenced by Jazz instruments in its early growth stage.
