Salsa is a popular form of social dance that originated in the Caribbean. The movements of salsa have origins in Puerto Rican bomba and plena, Cuban Son, cha-cha-cha, mambo and other dance forms. The dance, along with salsa music, originated in the mid-1970sin New York. In many styles of salsa dancing, as a dancer shifts their weight by stepping, the upper body remains level and nearly unaffected by the weight changes. Weight shifts cause the hips to move. Arm and shoulder movements are also incorporated.
