Step-by-step explanation:
Reggae, a popular music genre from Jamaica, is noted for the vocalist's poignant "hard edged" social commentary. Emerging in the 1960s, reggae has been significantly influential worldwide, elevating artists like Bob Marley and the Wailers to international fame. This genre features a distinctive rhythmic style with offbeat accents, which evolved from earlier genres such as ska and rocksteady. Reggae's association with the Rastafarian movement, or Rasta, adds a layer of cultural and spiritual depth to the music. Musicians across the board, from the Beatles to Eric Clapton, have incorporated reggae rhythms into their music, while groups outside of Jamaica, such as UB40, have helped popularize reggae on the world stage.
