Bob Marley is one of the most iconic figures in music, and his genre of choice was a combination of ska and reggae. Ska is a genre of music that originated in Jamaica in the late 1950s and is characterized by a walking bass line, offbeat rhythms, and horns. Reggae is a genre of music that developed in Jamaica in the late 1960s and is characterized by a slower tempo, accentuated offbeat rhythms, and a focus on social and political issues. Both ska and reggae were popularized by Bob Marley and have become synonymous with his name.
