Soul and R&B music evolved from African American musical traditions, blending gospel, blues, and jazz influences. These genres revolutionized popular music with emotive vocals, syncopated rhythms, and themes of love and social issues.

Motown Records popularized a polished soul sound, while Stax Records offered grittier Southern soul. The genres diversified over time, incorporating funk, hip-hop, and electronic elements, leading to contemporary R&B and neo-soul styles.
