Salsa dance movements originate from the Cuban Son dancing of the 1930s more specifically through the beat of Son Montuno with strong influences from the dance of Danzon, Mambo, Guaguanco and other Afro-Cuban folkloric dancing. Salsa is typically a partner dance, although there are recognized solo forms (Floor Shines/ Shines), line dancing (suelta), and Rueda de Casino, where groups of couples exchange partners in a circle. Women traditionally wear short/skirted latin outfits and men wear tight fitting shirts and pants.
Bachata is a style of dance that originated in the Dominican Republic and borrows from the cuban bolero. The basics to the dance are three-steps with Cuban hip motion, followed by a hip tap on the 4th beat. Bachata music developed in the Dominican Republic and has an accent in rhythm at every fourth count. Often, this is when dancers will tap-step & pop their hips. Women often wear short/skirted latin outfits and men are outfitted in tight fitting shirts and pants.
Mambo is a latin dance that developed in Cuba and officially began with a song called "Mambo" written in 1938. The song was a danzón, a dance form descended from European social dances, but was backed by rhythms derived from African folk music. The Ballroom version of Mambo forward breaks On 2, with a pause/chill on the 1 beat. The women traditionally wear short/skirted latin outfits and the men wear tight fitting shirts and pants to emphasis leg action and body movements.
