The term 'Forerunner of Rock Steady' can be summarized as SKA, a three letter acronym. SKA is a musical genre that originated in Jamaica in the late 1950s and is considered to be the precursor to rock steady and reggae. It is characterized by a walking bass line, guitar and piano offbeats, and a strong rhythm section. The genre has since spread around the world and has been embraced by many different cultures.
