从40年代后期的跳蓝调演变而来，R&B为摇滚乐奠定了基础。节奏布鲁斯保留了跳蓝调的节奏和驱动力，但它的乐器更少，重点是歌曲，而不是即兴创作。这是用一种坚持的后拍演奏的蓝调和弦变化。在50年代，R&B的主导者是像Ray Charles和Ruth Brown这样的歌手，以及像漂流者和杯垫这样的声乐组合。最终，R&B蜕变成了灵魂乐，比节奏布鲁斯的打桩节奏更时髦、更松散。Soul用来描述一些基于r&b的音乐风格。从在摩城的活跃，朗朗上口的行为，以角驱动，坚韧不拔的灵魂Stax/Volt，有一个巨大的多样性的灵魂。在60年代的前半段，灵魂音乐仍然接近它的R&B根源。然而，音乐家们把音乐推向不同的方向;通常，美国不同的地区产生了不同的灵魂。 In urban centers like New York, Philadelphia, and Chicago, the music concentrated on vocal interplay and smooth productions. In Detroit, Motown concentrated on creating a pop-oriented sound that was informed equally by gospel, R&B, and rock & roll. In the South, the music became harder and tougher, relying on syncopated rhythms, raw vocals, and blaring horns. All of these styles formed soul, which ruled the black music charts throughout the '60s and also frequently crossed over into the pop charts. During the '60s and '70s, soul began to splinter apart -- artists like James Brown and Sly Stone developed funk; Kenny Gamble and Leon Huff initiated Philly soul with the O'Jays and Harold Melvin & the Blue Notes; and later in the decade, danceable R&B became a mass phenomenon with the brief disco fad. During the '80s and '90s, the polished, less earthy sound of urban and quiet storm ruled the airwaves, but even then, R&B began adding stylistic components of hip-hop until -- by the end of the millennium -- there were hundreds of artists who featured both rapping and singing on their records.
