In the early 1950s, it was frequently applied to blues records. The term "rhythm and blues" has undergone a number of shifts in meaning. R&B lyrical themes often encapsulate the African-American experience of pain and the quest for freedom and joy, as well as triumphs and failures in terms of relationships, economics, and aspirations. In the commercial rhythm and blues music typical of the 1950s through the 1970s, the bands usually consisted of piano, one or two guitars, bass, drums, one or more saxophones, and sometimes background vocalists.

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. Rhythm and blues, often abbreviated as R&B or R'n'B, is a genre of popular music that originated in African-American communities in the 1940s. For the Japanese television station that uses the abbreviation RNB, see Nankai Broadcasting. For the modern style of R&B music, see Contemporary R&B.
