Also known as Salsa Monga (Limp Salsa) is a commercialized toned down version of salsa music that emerged in the mid 80's. Emphasis was taken away from the hard hitting orchestrations of the 60's, 70's and early 80's and focused mainly on the sex appeal of the front man or singer, usually a pretty boy or woman with no singing skills. It was an exploited venue that saw the likes of Marc Anthony, Eddie Santiago and a slew of forgettable figures. Many musicians in the genere saw it as the death of salsa music and desecration of the genere.
Salsa's closest relatives are Cuban mambo and the son orchestras of the early 20th century, as well as Latin jazz.
Salsa bands play a wide variety of songs, including pieces based on plenas and bombas, cumbia, vallenato and merengue; most songs, however, are modern versions of the Cuban son.
Salsa music is traditionally based on a 4/4 time signature, and is mostly phrased in groups of two bars (eight beats), such as recurring rhythmic patterns and main phrases of the chorus.
