Salsa is a popular form of social dance that originated in the Caribbean. The movements of salsa have origins in Cuban Son, cha-cha-cha, mambo and Puerto Rican bomba and plena and other dance forms. The dance, along with the salsa music, originated in the mid-1970s in New York.
The name Salsa (sauce) has been described as a dance since the mid-1800s. It evolved from earlier Cuban dance forms such as Son, Son Montuno, cha cha cha, Mambo and Puerto Rican bomba and plenty which were popular in the Caribbean, Latin America and the Latino communities in New York since the 1940s. Salsa, like most music genres, has gone through a lot of variation through the years and incorporated elements of Afro-Cuban and Afro-Caribbean dances such as Guaguancó and Pachanga. Different countries of the Caribbean and Latin America have distinct salsa styles of their own, such as Cuban, Cali Colombia, Puerto Rican, L.A. and New York styles.
There is some controversy surrounding the origins of the word "salsa". Some claim that it was based on a cry shouted by musicians while they were playing their music. Others believe that the term was created by record labels to better market their music, who chose the word "salsa" because of its spicy and hot connotations. Still, others believe the term came about because salsa dancing and music is a mixture of different styles, just like salsa or "sauce" in Latin American countries is a mixture of different ingredients.
Salsa is different everywhere. For example, Celia Cruz says she makes a Cuban style of salsa. It is aimed heavily towards the Afro-Latino communities. Her songs represent traditional Cuban sounds and customs. Most countries add a different twist to their salsa dance and music and that's what makes it so unique. In the US there are multiple styles in different areas that represent those communities.
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. The Cuban Casino style of salsa dancing involves significant movement above the waist, with up-and-down shoulder movements and shifting of the ribcage.
The arms are used by the "lead" dancer to communicate or signal the "follower," either in "open" or "closed" position. The open position requires the two dancers to hold one or both hands, especially for moves that involve turns, putting arms behind the back, or moving around each other, to name a few examples. In the closed position, the leader puts the right hand on the follower's back, while the follower puts the left hand on the leader's shoulder.
