'R&B' originates from the term 'rhythm and blues', which was coined in the United States in the 1940s to describe a style of music that combined elements of jazz, gospel, and blues.

'Rhythm and blues' was abbreviated to 'R&B' in the mid-20th century as the genre gained popularity.

Initially, it referred to a specific style of music, but over time it has come to encompass a broader range of musical styles that incorporate elements of soul, funk, and hip hop.
