Billboard’s Harlem Hit Parade became Rhythm and Blues in 1949
Rhythm and blues grew inside African American communities in the 1940s as labels marketed rocking, insistent Black music. Jerry Wexler is often credited with coining the phrase at Billboard in 1948, though the magazine had used it earlier; in 1949 Rhythm and Blues replaced the Harlem Hit Parade chart name.
Typical 1950s–1970s commercial bands mixed piano, guitars, bass, drums, and sax, sometimes with backing singers, rehearsed into hypnotic interlocking parts. Lyrics often tracked pain, freedom, racism, love, and joy. Great Migration cities—Chicago, Detroit, New York, Los Angeles, Washington—built new markets that blended jazz, blues, and urban grit. Mid-decade, after feeding rock and roll, R&B widened to cover electric blues, gospel, and soul strands; late-1980s contemporary R&B folded in funk, disco, and electronics.
Louis Jordan’s Tympany Five and Joe Turner’s big-band shout helped lay foundations; in 1948 Jordan dominated R&B chart tops with boogie-driven hits. Paul Williams’s The Huckle-Buck ruled nearly all of 1949 as a raunchy “dirty boogie.” The Rock & Roll Hall of Fame also flags James Brown and LaVern Baker among transformers toward rock and roll. Smithsonian writers call the style an amalgam of jump blues, swing, gospel, boogie, and blues across a thirty-year bridge from legal segregation into postwar popular culture. Billboard’s first chart of Black favourites, the 1942 Harlem Hit Parade, predates Wexler’s coinage, and the new label displaced the older trade phrase race music; RCA Victor meanwhile sold the same records as Blues and Rhythm. Ruth Brown, Little Richard, Fats Domino, Roy Brown and Etta James are counted among the style’s cornerstones. By the time disc jockey Alan Freed was using rock and roll on the mainstream airwaves around 1955, its sexual undertone had faded into simple dance slang. A newer contemporary R&B emerged in the late 1980s, blending funk, disco, soul and electronic sounds.
Afro-Cuban rhythms—habanera, tresillo, Jelly Roll Morton’s “Spanish tinge”—had flavoured African American music for generations; late-1940s New Orleans proved especially open as R&B coalesced. Robert Palmer treated R&B as music made by and for Black Americans, sometimes synonymous with jump blues, while AllMusic stresses stronger gospel DNA. Whatever the boundary fight, the name began as a marketing shelf and became a lineage still reinventing itself.
