Late 1940s
R&B originated in African-American communities in the 1940s. In 1948, RCA Victor was marketing black music under the name "Blues and Rhythm". In that year, Louis Jordan dominated the top five listings of the R&B charts with three songs, and two of the top five songs were based on the boogie-woogie rhythms that had come to prominence during the 1940s. Jordan's band, the Tympany Five (formed in 1938), consisted of him on saxophone and vocals, along with musicians on trumpet, tenor saxophone, piano, bass and drums. Lawrence Cohn described the music as "grittier than his boogie-era jazz-tinged blues". Robert Palmer described it as "urbane, rocking, jazz-based music ... [with a] heavy, insistent beat". Jordan's music, along with that of Big Joe Turner, Roy Brown, Billy Wright, and Wynonie Harris, before 1949, was referred to as jump blues. Then, Paul Gayten, Roy Brown, and others had had hits in the style now referred to as rhythm and blues. In 1948, Wynonie Harris's remake of Brown's 1947 recording "Good Rockin' Tonight" reached number two on the charts, following band leaderSonny Thompson's "Long Gone" at number one.
