The term Salsa is used for Latin music, sounds from Cuba and the Caribbean. The word was used before the music and dance were a style. What it exactly defines is a continues discussion. And who launched the term is buried in history. But several musicians are using salsa.

There was a Son with the name Salsa.
salsahmIgnacio Piñero used the word in his song "Echale Salsita" in 1928 (take some sauce).
He was referring to the exciting "instrumental sauce" of the multitude of harmoniously combined instruments that helped to digest harsh daily realities.
Benny Nore and Celia Cruz often called "Salsa, salsa' in their songs to whip implementation.
A Venezuelan used the word for a radio program with music as pachangas, rumbas, boleros, chachacha 's, mambo's.

No one had the intention to launch a term or style, it is simply unmatched! And not all artists were excited.
Cheo Feliciano (Puerto Rican singer): "I do not like the name Salsa. This way the youth tomorrow will never come to know that the son montuno, the guaguanco, the Danzon, the guaracha, rumba, mambo existed.. "
Ray Baretto (Puerto Rican musician): "The word Salsa is primarily a new cover name which allows to identify those who do not know her well. A question of marketing the music."
Tito Puente: "Salsa I do on my food, this music is just Afro - Cuban music."

A beautiful story dates back to 1966, when Richie Ray and Bobby Cruz were interviewed by radio personality Phidias Danilo Escalona for his "La Hora del Sabor y el Bemba" program during the first tour with their Latin American band in Caracas, Venezuela.
The DJ asked them to nominate their specific music. They replied that their music was like "ketchup". The English ignorant DJ asked them: "What is ketchup? " Both of them said: "Salsa" (Spanish for sauce). To which the DJ announced, "The music of Richie Ray and Bobby Cruz is named salsa." After the interview, he told them that he would call his radio program "La Hora del Sabor, La Salsa y el Bemba".

Another story claims that he had a popular radio program "La hora de la Salsa", which has been sponsored in 1962 by a manufacturer of spicy tomato sauce.
