What song originated R&B?

Answer 1

black people in essence created it and was consisted of genres: jazz, blues, and gospel since the 1940s when the term was pegged so there is no particular song.

Answer 2

Rocket 88
Rocket 88" is a rhythm and blues song that was first recorded at Sam Phillips' recording studio in Memphis, Tennessee, on 3 or 5 March (accounts differ) 1951. It is claimed by some, including Phillips — later to become owner of Sun Records, and pioneer rock and roll record producer — to be the "first rock and roll song".

The original version of the record was credited to "Jackie Brenston and his Delta Cats", but that band did not actually exist. The song was written by Ike Turner at the Riverside Hotel in Clarksdale, Mississippi - though apparently based on the 1947 song "Cadillac Boogie" by Jimmy Liggins - and recorded by him with his band, the Kings of Rhythm. Jackie Brenston (1930-1979) was a saxophonist with Turner who also sang the vocal on "Rocket 88", a hymn of praise to the joys of the Oldsmobile "Rocket 88" automobile (see: Oldsmobile 88), which had just been introduced in 1949. Brenston was given author credit rather than Turner; it is now agreed that Brenston's contribution was overstated for financial reasons.

Working from the raw material of jump blues and swing combo music, Turner made it even rawer, starting with a strongly stated back beat by drummer Willie Sims, and superimposing Brenston's enthusiastic vocals, his own piano, and tenor saxophone solos by Raymond Hill. The song also features one of the first examples of distortion, or fuzz guitar ever recorded, played by the band's guitarist Willie Kizart. The legend of how the sound came about says that a tube amplifier was damaged on Highway 61 when the band was driving from Mississippi to Memphis, Tennessee but Phillips liked the sound and used it. (Link Wray had a similar story.)

Answer 3

There was no single song just like there was no individual artist that could be pinned down as the definitive song/person when R&B was created. It just evolved from styles that came before. James Brown was more soul as was Aretha Franklyn. The Temptations (and others like The Supremes) and Barry Gordy at Motown perfected it.

Answer 4

there was no song that originated R&B. there was a singer named james brown. he beame famous in the early 1950's. other genres of music that originated from his style are soul, rap, funk and hip-hop.
