BACHATA.
This kind of music comes from Dominican Republic. Bacgata dance began in the 50's. It's belived this dance has it's origin on othrer dances such  as Boleros, pasillo and cuba's dances.At the beginning bachata music was colled "boleros de guitarra".
The bachata was developing in the Santo Domingo' pubs in adiction other thing which is really interesting is thta bachata music was colled "musica de amargue".
In the 80's the bachata arrived to the media besides one of the most representative singer of that age was Juan Luis Guerra who is a really good bachata's singer.
About Colombia it was Juan Luis who brought bachata music to Colombia. Becouse his songs started to plays in Colombia.
