In the 1950s, the United States saw the rise of teen culture and rock 'n roll, while jazz clubs and ballads were also popular. Many musical styles flourished and combined in the 1940s and 1950s, most likely because of the influence the radio had in creating a mass market for music. World War II caused great social upheaval, and the music of this period shows the effects of that upheaval.

Classic pop

Popular music, or "classic pop," dominated the charts for the first half of the 1950s. Vocal-driven classic pop replaced Big Band/Swing at the end of World War II, although it often used orchestras to back the vocalists. 1940s style Crooners vied with a new generation of big voiced singers, many drawing on Italian bel canto traditions. Mitch Miller, A&R man at the era's most successful label, Columbia Records, set the tone for the development of popular music well into the middle of decade. Miller integrated country, Western, rhythm & blues, and folk music into the musical mainstream, by having many of his label's biggest artists record them in a style that corresponded to Pop traditions. Miller often employed novel and ear-catching arrangements featuring classical instruments (whooping french horns, harpsichord), or sound effects (whip cracks). He approached each record as a miniature story, often "casting" the vocalist according to type. (Mitch) Miller and the producers who followed his model were creating a new sort of pop record. Instead of capturing the sound of live groups, they were making three-minute musicals, matching singers to songs in the same way that movie producers matched stars to film roles. As Miller told 'Time' magazine in 1951, 'Every singer has certain sounds he makes better than others. Frankie Laine is sweat and hard words - he's a guy beating the pillow, a purveyor of basic emotions. Guy Mitchell is better with happy-go-lucky songs; he's a virile young singer, gives people a vicarious lift. Rosemary Clooney is a barrelhouse dame, a hillbilly at heart.' It was a way of thinking perfectly suited to the new market in which vocalists were creating unique identities and hit songs were performed as television skits."How The Beatles Destroyed Rock 'n' Roll," Elijah Wald, Oxford University Press, 2009, p. 162.

Whereas Big Band/Swing music placed the primary emphasis on the orchestration, post-war/early 1950s era Pop focused on the song's story and/or the emotion being expressed. By the early 1950s, emotional delivery had reached its apex in the miniature psycho-drama songs of writer-singer Johnnie Ray. Known as 'The Cry Guy' and 'The Prince of Wails,' Ray's on-stage emotion wrought 'breakdowns' provided a release for the pent-up angst of his predominantly teenaged fans. As Ray described it, "I make them feel, I exhaust them, I destroy them.'"Cry: The Johnnie Ray Story," Jonny Whiteside, Barricade Books, October 1994. It was during this period that the fan hysteria, which began with Frank Sinatra during the Second World War, really began to take hold.

Although often ignored by musical historians, Pop music played a significant role in the development of Rock 'n' Roll as well:

[Mitch] Miller also conceived of the idea of the pop record 'sound' per se: not so much an arrangement or a tune, but an aural texture (usually replete with extramusical gimmicks) that could be created in the studio and then replicated in live performance, instead of the other way around. Miller was hardly a rock 'n' roller, yet without these ideas there could never have been rock 'n' roll. 'Mule Train', Miller's first major hit (for Frankie Laine) and the foundation of his career, set the pattern for virtually the entire first decade of rock. The similarities between it and, say, 'Leader of the Pack,' need hardly be outlined here."Sinatra: The Song Is You," Will Friedwald, Da Capo Press, 1997, p. 174.

Patti Page kicked things off with what would become the decade's biggest hit, "Tennessee Waltz." Her other hits from this period included: "Mister and Mississippi," "Mockin' Bird Hill," "Detour," "(How Much Is That) Doggie in the Window," and "Old Cape Cod." Frankie Laine's 1949 hits, "That Lucky Old Sun (Just Rolls Around Heaven All Day)" and "Mule Train," were still riding high on the charts when the decade began. He continued to score with such hits as: "Georgia On My Mind," "Cry of the Wild Goose," "Jezebel," "Rose, Rose, I Love You," "Jealousy (Jalousie)," "High Noon (Do Not Forsake Me)," "I Believe," "Granada," "Moonlight Gambler," and "Rawhide." Johnnie Ray had a long run of hits in the early half of the decade, often backed by The Four Lads, including: "Cry," "The Little White Cloud That Cried," "Walking My Baby Back Home," "Please, Mr. Sun," and "Just Walkin' in the Rain." The Four Lads racked up some hits on their own with "Who Needs You," "No, Not Much," "Standin' on the Corner," and "Moments to Remember." Nat "King" Cole dominated the charts throughout the decade with such timeless classics as "Unforgettable," "Mona Lisa," "Too Young," "Darling, Je Vous Aime Beaucoup," "Pretend," "Smile," and "A Blossom Fell." Perry Como was another frequent visitor to the charts with hits like: "If," "Round and Round," "Don't Let the Stars Get in Your Eyes," "Tina Marie," "Papa Loves Mambo," and "Catch a Falling Star."

Other major stars in the early 1950s included Frank Sinatra ("Young at Heart," "Three Coins in the Fountain," "Witchcraft"), Tony Bennett ("Cold, Cold Heart," "Because of You," "Rags to Riches"), Kay Starr ("Bonaparte's Retreat," "Wheel of Fortune," "Rock and Roll Waltz"), Rosemary Clooney ("Come On-a My House," "Mambo Italiano," "Half as Much," "This Ole House"), Dean Martin ("That's Amore," "Return to Me," "Sway"), Georgia Gibbs ("Kiss of Fire," "Dance With Me, Henry," "Tweedle Dee"), Eddie Fisher ("Anytime," "Wish You Were Here," "Thinking of You," "I'm Walking Behind You," "Oh! My Pa-Pa," "Fanny"), Teresa Brewer ("Music! Music! Music!," "Till I Waltz Again With You," "Ricochet (Rick-O-Shay)"), Doris Day ("Secret Love," "Whatever Will Be Will Be (Que Sera Sera)," "Teacher's Pet"), Guy Mitchell ("My Heart Cries for You," "The Roving Kind," "Pittsburgh, Pennsylvania," "Singing the Blues"), Bing Crosby ("Play a Simple Melody with son Gary Crosby, "True Love with Grace Kelly), Dinah Shore ("Lavender Blue"), Kitty Kallen ("Little Things Mean a Lot"), Joni James ("Have You Heard," "Wishing Ring," "Your Cheatin' Heart"), Peggy Lee ("Lover," "Fever"), Julie London ("Cry Me a River"), Toni Arden ("Padre"), June Valli ("Why Don't You Believe Me"), Arthur Godfrey ("Slowpoke"), Tennessee Ernie Ford ("Sixteen Tons"), Les Paul and Mary Ford ("Vaya Con Dios," "Tiger Rag"), and vocal groups like The Mills Brothers ("Glow Worm"), The Weavers "(Goodnight Irene"), The Four Aces ("Love Is a Many-Splendored Thing", "(It's No) Sin"), The Chordettes ("Mister Sandman"), Fontane Sisters ("Hearts of Stone"), The Hilltoppers ("Trying," "P.S. I Love You"), The McGuire Sisters ("Sincerely," "Goodnite, Sweetheart, Goodnite," "Sugartime") and The Ames Brothers ("Ragmop", "The Naughty Lady of Shady Lane").

Classic pop declined in popularity as rock and roll entered the mainstream and became a major force in American record sales. Crooners such as Eddie Fisher, Perry Como, and Patti Page, who had dominated the first half of the decade, found their access to the pop charts significantly curtailed by the decade's end.R. S. Denisoff, W. L. Schurk, Tarnished gold: the record industry revisited (Transaction Publishers, 3rd edn., 1986), p. 13. However, new Pop vocalists continued to rise to prominence throughout the decade, many of whom started out singing Rock 'n' Roll. These include: Pat Boone ("Don't Forbid Me," "April Love," "Love Letters in the Sand"), Connie Francis ("Who's Sorry Now," "Among My Souvenirs," "My Happiness"), Gogi Grant ("Suddenly There's a Valley," "The Wayward Wind"), Bobby Darin ("Dream Lover," "Beyond the Sea," "Mack the Knife"), and Andy Williams ("Canadian Sunset," "Butterfly," "Hawaiian Wedding Song"). Even Rock 'n' Roll icon Elvis Presley spent the rest of his career alternating between Pop and Rock ("Love Me Tender," "Loving You," "I Love You Because"). Pop would resurface on the charts in the mid-1960s as "Adult Contemporary."

Rock and roll

Rock and roll dominated popular music in the latter half of the 1950s. The musical style originated and evolved in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various black musical genres of the time, including rhythm and blues and gospel music; with country and western and Pop."The Roots of Rock", Rock and Roll Hall of Fame, retrieved May 4, 2010. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music,"Rock (music)", Encyclopædia Britannica, retrieved June 24, 2008. though the terms "rocking" and "rolling" were being used in boogie-woogie and religious music for decades before that.

The 1950s saw the growth in popularity of the electric guitar (developed and popularized by Les Paul). Paul's hit records like "How High the Moon," and "The World Is Waiting for the Sunrise," helped lead to the development of a specifically rock and roll style of playing of such exponents as Chuck Berry, Link Wray, and Scotty Moore.J. M. Curtis, Rock Eras: Interpretations of Music and Society, 1954–1984 (Madison, WI: Popular Press, 1987), , p. 73. Chuck Berry, who is considered to be one of the pioneers of Rock and roll music, refined and developed the major elements that made rock and roll distinctive, focusing on teen life and introducing guitar solos and showmanship that would be a major influence on subsequent rock music.M. Campbell, ed., Popular Music in America: And the Beat Goes on (Cengage Learning, 3rd edn., 2008), pp. 168–9.

Artists such as Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, Big Joe Turner, and Gene Vincent released the initial rhythm and blues-influenced early rock and roll hits. Rock and roll forerunners in the popular music field included Johnnie Ray, The Crew-Cuts, The Fontane Sisters, and Les Paul and Mary Ford. The Rock and Roll Era is generally dated from the March 25, 1955 premiere of the motion picture, "The Blackboard Jungle." This film's use of Bill Haley and His Comets' "(We're Gonna) Rock Around the Clock" over its opening credits, caused a national sensation when teenagers started dancing in the aisles.

Pat Boone became the first rock and roll teen idol in 1955 with heavily Pop-influenced "covers" of R&B hits like "Two Hearts, Two Kisses (Make One Love)," "Ain't That a Shame", and "At My Front Door (Crazy Little Mama)." Boone's traditional approach to rock and roll, coupled with his All-American, clean-cut image helped bring the new sound to a much wider audience. Elvis Presley, who began his career in the mid-1950s, soon became the leading figure of the newly popular sound of rock and roll with a series of network television appearances, motion pictures, and chart-topping records. His energized interpretations of songs, many from African American sources, and his uninhibited performance style made him enormously popular—and controversial during that period. Boone and Presley's styles/images represented opposite ends of the burgeoning musical form, which competed with one another throughout the remainder of the decade.
