Reggae is a music genre developed in Jamaica. Reggae may be used in a broad sense to refer to most types of Jamaican music, including ska, rocksteady, dub, dancehall and ragga. The term may also be used to distinguish a particular style that originated in the late 1960s. Reggae is founded upon a rhythm style which is characterized by regular chops on the back beat, played by a rhythm guitarist and known as the "bang", and a bass drum often hitting on the third beat of each measure, known as "one drop." Characteristically, this beat is slower than in reggae's precursors, ska and rocksteady. Reggae is often associated with the Rastafarian movement, which influenced many prominent r m reggae musicians in the 1970s and 1980s. However, the subject matter of reggae songs deals with many subjects other than Rastafari, with love songs, sexual themes and broad social commentary being particularly well-r epresented.
