The term REGGAE FORERUNNER can be solved by the three-letter word SKA. Reggae is a genre of music that originated in Jamaica in the late 1960s, and ska is a precursor to reggae that developed in Jamaica in the late 1950s. Ska is characterized by a walking bass line, offbeat rhythms, and a strong emphasis on the offbeat. It was popularized in the UK in the early 1960s and has since become an important part of Jamaican culture.
