R&B stands for Rhythm and Blues. It is a genre of popular music that originated in African American communities in the 1940s. R&B music typically features a strong backbeat, prominent basslines, and the use of call-and-response patterns. It often incorporates elements of gospel, blues, and jazz. Over the years, the meaning of R&B has evolved and it has become an umbrella term for various sub-genres like Soul, Funk, and Neo Soul. Today, R&B is characterized by its emphasis on vocal harmonies, emotional lyrics, and smooth production.
