Developed in the late 1940s and early 1950s, R & B Soul Music is actually the popular music by the African Americans. The term was used by record firms to describe recordings targeted at African Americans at a time when rocking and jazz based music was becoming more popular. This kind of music also gave rise to the rise of rock and roll; however the phrase R&B began to be associated with music styles that tended to develop from electric blues, apart from gospel and soul music. Now since 1990s, R&B is mainly used to refer to the latest version of soul and funk-influenced pop music.

It basically took the place of the phrase ""race music"" that was developed by the black community, but was considered offensive in the post-war world. Some experts describe the term as any music that is composed by the blacks. Others opine that the term was coined for industry convenience. It was related to all music by blacks except for classical music and spiritual music apart from any gospel song ranked high enough in popularity to be included in the charts.
In 1948, a firm was churning out music using the label Blues and Rhythm. The popularity of R & B Soul Music made the Film producers take the respective musicians as ""rock n roll"" musicians in 1956.
