Style of U.S. popular music sung and performed primarily by African American musicians, having its roots in gospel music and rhythm and blues. The term was first used in the 1960s to describe music that combined rhythm and blues, gospel, jazz, and rock music and that was characterized by intensity of feeling and earthiness. In its earliest stages, soul music was found most commonly in the South, but many of the young singers who were to popularize it migrated to cities in the North. The founding of Motown in Detroit, Mich., and Stax-Volt in Memphis, Tenn., did much to encourage the style. Its most popular performers include James Brown, Ray Charles, Sam Cooke, and Aretha Franklin.
