Salsa evolved from 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.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.
