"Reggae is a music genre first developed in Jamaica in the late 1960s. While sometimes used in a broader sense to refer to most types of Jamaican music, the term reggae more properly denotes a particular music style that originated following on the development of ska and rocksteady.
Reggae is most easily recognized by the rhythmic accents on the off-beat, usually played by guitar or piano (or both), known as the skank"
