Salsa music is a general term referring to a genre that is essentially Cuban and Puerto Rican popular dance music. The term salsa was initially promoted and marketed in New York City during the 1970s. Salsa comprises various musical genres including the Cuban son montuno, guaracha, chachachá, mambo, and to a certain extent bolero. Salsa is the product of genres such as the Puerto Rican bomba and plena. Latin jazz, which was also developed in New York City, has had a significant influence on salsa arrangers, piano guajeos, and instrumental soloists.
