Hi, Jag, Hi Yuca, don´t know if I started saying so, but definitely I will continue to do so: Cumbia is Cumbia, Zouk is Zouk, Casino is Casino, Mambo classico is Mambo classico.
But Salsa isn´t anything specific. You are allowed to use this word as you like to.
There are musicians who say definitively that , Salsa is NOT a musical format. Going on to say, as many have since said, a word coined by Fania, to re-brand Mambo.
Having said that, todays music, by and large, is different in many or some respects, so.... re- lablelling with a new name ,does serve a purpose. It, at its very least, describes the current dance ,thats evolved from a predecessor ( Mambo ) .Re-placing that name with salsa, seems to be quite appropriate, and if not, what name would you suggest ?? .
And, there are many that feel that,ALL the music in the genre, is a Son based concept.So should we say we are dancing Son ?.. well, there is a dance form that already exists by that name, that is nothing like salsa /mambo.
Music and dance, are both very complex "animals " and any attempt to classify them definitively, seldom gets resolved.
The present day nomenclature ,has been accepted, by and large, on a world wide basis, a "fete acommple'... " no?.( not sure about the grave accents, etc !
