Tutti Frutti is a song written by Little Richard and Dorothy LaBostrie, recorded in 1955, which was his first major hit. With its energetic refrain, often transcribed as "A-wop-bop-a-loo-mop-a-lop-bam-boom!" (a verbal rendition of a drum pattern that Little Richard had imagined), and its hard-driving sound and wild lyrics, it became not only a model for many future Little Richard songs, but also for rock and roll itself. The song introduced several of rock music's most characteristic musical features, including its loud volume, powerful vocal style, and distinctive beat and rhythm. In 2007, an eclectic panel of renowned recording artists ranked "Tutti Frutti" at No. 1 on Mojo'''s "The Top 100 Records That Changed The World" and hailed the recording as "the sound of the birth of rock and roll". In 2010, the U.S. Library of Congress National Recording Registry added the recording to its registry, claiming the "unique vocalizing over the irresistible beat announced a new era in music". In April 2012, Rolling Stone magazine declared the refrain "the most inspired rock lyric ever recorded". Original recording by Little Richard Although "Little Richard" Penniman had recorded for RCA and Peacock Records since 1951, his records had been relatively undistinguished and did not result in the commercial success for which his producers hoped. In February 1955, he sent a demo tape to Specialty Records, which was heard by Specialty owner Art Rupe. Rupe heard promise in the tapes and arranged a recording session for Little Richard at Cosimo Matassa's J & M Studio in New Orleans in September 1955, with Robert "Bumps" Blackwell as producer and Fats Domino's backing band. The band included Lee Allen and Alvin "Red" Tyler on saxophones, Huey Smith on piano, Frank Fields on double bass, Justin Adams on guitar and Earl Palmer on drums.Penniman, Richard Wayne.

During a lunch break, he started pounding a piano and singing a ribald song that he wrote and composed, and which he had been performing live for a few years. According to some accounts, he first wrote and performed the song while working as a janitor in a bus station. The song that he sang was a piece of music that he "had polished in clubs across the South."
