The term 'Jamaican Beat' refers to the popular music genre of ska, which originated in Jamaica in the late 1950s. Ska is a style of music that combines elements of Caribbean mento and calypso with American jazz and rhythm and blues. It is characterized by a walking bass line accented with rhythms on the off-beat. Ska has become a global phenomenon, with many different styles and subgenres emerging over the years. The term 'Ska' is derived from the Jamaican patois word 'skavoovie, ' which means 'to move quickly.'
