Bachata music originated in the Dominican Republic in the first half of the 20th century.
It consists of a slow, sensual beat, romantic or bittersweet lyrics, and instrumentation anchored by either acoustic or electric guitar.
In Bachata dancing, there are three different Bachata styles, but they can all be incorporated depending on the music playing. There is Dominican Bachata (more footwork and musicality), Sensual Bachata (more fluid-motion, more body rolls, slower & sensual moves) and Urban Bachata (more patterns, more partner work & more turns).
Here are some examples of Bachata Music, and some Bachata Dancing.
