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-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. Salsa dance socials are commonly held in night clubs, bars, ballrooms, restaurants, and outside, especially when part of an outdoor festival.
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. Salsa generally uses music ranging from about 150 bpm (beats per minute) to around 250 bpm, although most dancing is done to music somewhere between 160–220 bpm. The basic Salsa dance rhythm consists of taking three steps for every four beats of music. The odd number of steps creates the syncopation inherent to Salsa dancing and ensures that it takes 8 beats of music to loop back to a new sequence of steps.
Salsa evolved from earlier Cuban dance forms such as Son, Son Montuno, cha cha cha, Mambo and Puerto Rican Bomba and Plena which were popular in the Caribbean, Latin America and the Latino communities in New York since the 1940s. Salsa, like most music genres and dance styles, has gone through a lot of variation through the years and incorporated elements of other Afro-Caribbean dances such as Pachanga. Different regions of Latin America and the United States have distinct salsa styles of their own, such as Cuban, Puerto Rican, Cali Colombia, where the World master Dancers are in the best in the World. L.A. and New York styles.
There is some controversy surrounding the origins of the word "salsa," which has been ascribed to the dance since the mid-1800s. 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, singer Celia Cruz described her music as a Cuban style of salsa. Her songs represent traditional Cuban sounds and customs. In the United States, there are multiple styles in different regions of the country.
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.
In the original Latin American form, the forward/backward motion of salsa is done in diagonal or sideways with the 3-step weight change intact.
In some styles of salsa, such as the New York style, the dancers remain mostly in front of one another (switching places), while in Latin American styles, such as Cuban style, the dancers circle around each other, sometimes in 3 points. This circular style is inspired by 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. 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 their home territory. Characteristics that may identify a style include: timing, basic steps, foot patterns, body movement, 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 Puerto Rico, Cuba and surrounding Caribbean islands.Source: Wikipedia
