Research and Planning: R&B

Rhythm and blues, often abbreviated to R&B and RnB, is a genre of popular African-American music that originated in the 1940s.^[1] The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when "urbane, rocking, jazz based music with a heavy, insistent beat" was becoming more popular.^[2]
The term has subsequently had a number of shifts in meaning. In the early 1950s, the term rhythm and blues was frequently applied to blues records.^[3] Starting in the mid-1950s, after this style of music contributed to the development of rock and roll, the term "R&B" became used to refer to music styles that developed from and incorporated electric blues, as well as gospel and soul music. By the 1970s, rhythm and blues was used as a blanket term for soul and funk. In the 1980s, a newer style of R&B developed, becoming known as "Contemporary R&B".
