Rhythm and Blues also known as R&B, R'n'B or RnB it is a style of music developed by African Americans that combines blues and jazz, characterized by strong backbeat and repeated variations on syncopated instrumental phrases.The term replaced ‘race music’ and was supplanted by ‘soul’. Rhythm-and-blues grew out of the blues and related styles but is played by an ensemble, typically of a lead singer or instrumentalist, a rhythm section (bass, drums and some combination of piano, electric organ and electric guitar) and a group consisting of voices, wind instruments, guitar or organ.
