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 the salsa music, originated in the mid-1970s in New York. Different regions of Latin America and the United States have distinct salsa styles of their own, such as Cuban, Puerto Rican, Cali Colombia, L.A. and New York styles.
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.
