Bachata Sensual is inspired from Zouk btw
Originally Zouk was not a dance!
It was just a word to designate french caribbean parties.
So Zouk parties were a mixture of styles, and one of them was traditional Bachata from the Dom. Republic.
Then this band created the original Zouk music style, which has nothing to do with brazilian Zouk:
Kassav
Zouk only became a dance style when brazilians incorporated lambada into it, after lambada died as a rhytim and music genre in the early 90s.
After a while, it added elements of gafieira (traditional samba dance style), jazz and even hip hop and other urban styles.
Then the modern sensual zouk we know today was born.
BTW, brazilian zouk does not have a proper music style...it just uses every sensual music or remix that has a similar sexy trance pattern.
Sensual bachata is completely different.
It is a music and dance style.
Yes, it is inspired by a lot of rythyms and constatnly evolving, but only very very recently it got few moves from brazilian Zouk.
Sensual bachata was born way before brazilian zouk was consolidated as a dance style.
