Salsa music is a diverse and predominantly Latin American and Caribbean genre that is popular across Latin America and among Latinos abroad. Salsa incorporates multiple styles and variations; the term can be used to describe most any form of popular Cuban-derived genre, such as chachachá and mambo. Most specifically, however, salsa refers to a particular style developed in the 1960s and '70s by Cuban and Puerto Rican immigrants to the New York City area, and stylistic descendants like 1980s salsa romantica. The style is now practiced throughout Latin America, and abroad. Salsa's closest relatives are Cuban mambo and the son orchestras of the early 20th century, as well as Latin jazz. The terms Latin jazz and salsa are sometimes used interchangeably; many musicians are considered a part of either, or both, fields, especially performers from prior to the 1970s.
Salsa is the primary music played at Latin dance clubs and is the "essential pulse of Latin music", according to Ed Morales, while music author Peter Manuel called it the "most popular dance (music) among Puerto Rican and Cuban communities, (and in) Central and South America", and "one of the most dynamic and significant pan-American musical phenomena of the 1970s and 1980s". Modern salsa remains a dance-oriented genre and is closely associated with a style of salsa dancing.
