R&B originated from the blending of blues and gospel music styles by African Americans who migrated from the rural South to northern cities in the 1930s-1940s. It was characterized by a strong rhythmic beat and focus on emotional experiences. Early influential R&B artists included Ray Charles, BB King, and James Brown. Motown Records popularized R&B in the 1960s with its soulful sound. Contemporary R&B since the 1990s draws from earlier soul and funk influences.
