The term MUSICAL KIN OF REGGAE can be solved by the three-letter word SKA. Ska is a genre of music that originated in Jamaica in the late 1950s and is closely related to reggae. It is characterized by a walking bass line, accented guitar or piano rhythms on the offbeat, and a drumming style that uses a mix of accents on the backbeat and open hi-hat on the upbeat. Ska has been popularized around the world and has had a major influence on genres such as punk rock, rocksteady, and 2 Tone.
