Rhythm and blues, often abbreviated to R&B or RnB, is a genre of popular African-American music that originated in the 1940s. 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.
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. 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".
Contemporary R&B has a polished record production style, drum machine-backed rhythms, an occasional saxophone-laced beat to give a jazz feel (mostly common in contemporary R&B songs prior to the year 1995), and a smooth, lush style of vocal arrangement. Electronic influences are becoming an increasing trend, and the use of hip hop or dance-inspired beats are typical, although the roughness and grit inherent in hip hop may be reduced and smoothed out. Contemporary R&B vocalists are often known for their use of melisma, popularized by vocalists such as Michael Jackson, Brian McKnight, Usher, Trey Songz and Mariah Carey.
