This is a timeline of music in the United States from 1920 to 1949.

1920

• Vaudevillean Mamie Smith records "Crazy Blues" for Okeh Records, the first blues song commercially recorded by an African-American singer,^[1][2][3] the first blues song recorded at all by an African-American woman,^[4] and the first vocal blues recording of any kind,^[5] a few months after making the first documented recording by an African-American female singer,^[6] "You Can't Keep a Good Man Down" and "That Thing Called Love", which were successful enough for Okeh to commission "Crazy Blues".^[3] Stylistically, it resembles other vaudeville music of the era, but it borrows a poetic and melodic form from African-American folk music, as well as elements of unrelated "field-holler" vocal practices. More than its traditional predecessors, this mixture would come to define and epitomize the blues for later generations. The song^[7] becomes a surprising commercial success that would open up the market for African-American music^[1][8] by selling more than 8,000 copies a week for several months.^[3] It is followed by a string of hits by African-American women singers.^[9][10][11]
• A paper shortage contributes to a cost increase and a downturn in the sheet music publishing industry.^[12]
• Joseph Patek forms a family band that will become one of the longest-lasting and most influential Czech-Texan groups.^[13]

• Michigan and Wisconsin organize their first state-sponsored band contests.^[16]
• Carl Fischer Music publishes the first full band music scores in the United States.^[16]

Early 1920s music trends

In jazz bands, the cornetist becomes more and more frequently assigned to the melody of a piece, rather than shifting that responsibility among various instrumentalists.[17] American audiences begin to turn away from predominately German classical music towards works by the like of Frenchman Erik Satie and the Russian Alexander Scriabin.[18] An organized country music industry begins to evolve, through commercial recording and radio broadcasting.[19] Austrian composer Arnold Schoenberg begins advocating serialism, a composition technique that will come to dominate American classical music later in the 20th century.[20] The creative peak of jazz in Chicago.[21] A printers strike and paper shortage decimates the music publishing industry by raising costs, as customers are beginning to focus more on recordings than sheet music.[22] The golden age of the "black female blues singer" begins and ends.[23] American public schools begin offering music instruction for band and orchestra.[16] The Flanagan Brothers begin recording prolifically with great success. Mike Flanagan is the most popular Irish banjoist of the era.[24]

• Jelly Roll Morton makes his first recordings, as a jazz band member and as a solo pianist, and begins publishing songs through the Melrose Brothers Music Company.^[69] Morton is the "first to perceive and define the distinction between ragtime and jazz, insisting that the latter, whatever its sources or borrowings, was a new type of music that transformed what it absorbed".^[70] He is working with the New Orleans Rhythm Kings, the first Chicago-based white jazz band to record, using a black group (King Oliver's Creole Jazz Band) as a model. Morton's recording with the New Orleans Rhythm Kings constitutes the first "interracial recording sessions".^{[70][71][72][73]}
• King Oliver's Creole Jazz Band, performing at the Lincoln Gardens in Chicago, records with Gennett Studios, resulting in a set of recordings that are "landmark(s) in the history of jazz... the first major set of recordings by black jazz musicians".

• The success of Fiddlin' John Carson marks the beginning of the development of commercial country music and recorded old-time music.^[77]
• George Gershwin accompanies singer Eva Gauthier at a concert that is an "important event in America's musical history" because it helped to bridge the gap between popular and classical music.^[78]

1924

• The end of the Tin Pan Alley-led fad for blues and blues-like songs among mainstream listeners.^[1]
• George Gershwin premiers Rhapsody in Blue, an historically significant piece^[83] that fused three strands of American music: modernist classical music, instrumental jazz and popular blues; the piece "played a role in defining American musical modernism" in the 1920s,^[84] though it was "probably the most successful work in the movement to bring jazz into the concert hall", it is "better known today through lush arrangements for full symphony orchestras that have necessarily smoothed out the vernacular idiosyncrasies of its original performance style.^[85]

1925

Mid-1920s music trends

Henry Ford helps usher in what he refers to as a "square dance revival".[115] Scholars and collectors of folk songs become increasingly concerned about the authenticity of the blues they were recording and describing.[116] Hall Johnson and Eva Jessye lead a number of professional choirs to fame, bringing media attention to the concert-arranged African-American spiritual.[38] Sylvester Weaver, Lonnie Johnson and Papa Charlie Jackson are among a number of male solo vaudeville performers to begin recording attempts at popular blues, but Blind Lemon Jefferson's recordings in 1925 kicked off a wave of like-minded acts.[10] Record companies begin recording and marketing to Mexican Americans in California.[117] A more traditional sound in Finnish-American commercial recordings supplants the earlier format, which was based around semi-classical performance.[96] With the advent of national radio broadcasting companies, large businesses begin to sponsor a single show in its entirety. By 1927, as much as half of the total budget at major advertising companies is spent on radio.[118] The Aeolian Company's Pianola, a barrel organ, becomes widespread. The barrel organ will do more to spread musical knowledge in the United States than anything until the gramophone.[119]

• Louis Armstrong begins recording with his Hot Five and Hot Seven bands, for OKeh in Chicago. These resulting records are widely influential and establish the early jazz style,^[123][124] and helped launch Armstrong's career, which will eventually make him "one of the best-known and best-loved entertainers in the world".^[125] Music historian Richard Crawford has called these recordings "an enduring contribution to music history (that transcend) categorical boundaries to introduce a powerful new, utterly American mode of expression".^[126] The recordings establish Armstrong's career as the first virtuoso soloist in jazz, and move the field from one based on collective improvisation among all members of an ensemble to one in which one or more individual performers lead the performance through improvising.^{[127][128][129]} The Hot Five was Kid Ory, Johnny Dodds, Lil Hardin and Johnny St Cyr, while the Hot Seven added Pete Briggs and Baby Dodds, replacing Ory with John Thomas.^[130]

• Dock Walsh becomes one of the first to record three-finger banjo picking.^[141]
• Students at the Moody Bible Institute broadcast the first gospel music on the radio, on student station WNBL.^[142]
• George Antheil's Ballet mécanique is finished; it was intended to accompany a Fernand Léger film, but was later adapted into a complete composition, using "eight pianos, pianola, eight xylophones, two electric doorbells, percussion, wind machine, and 'airplane propellor', (described as) 'an adapted fan with a forty-eight-inch reach, six vicious blades, and a capacity of 4,000 revolutions per minute'". The piece will make Antheil "internationally notorious".^[143] The work may also be the "first use of (long periods of silence) for all instruments".^[144]
• Blind Lemon Jefferson begins making his first recordings, for Paramount Records, which include his first two hits, "Booster Blues" and "Dry Southern Blues".

• Bix Beiderbecke makes a series of recordings with Frank Trumbauer; though Beiderbecke would remain fairly obscure during his lifetime, he will go on to be remembered as perhaps the first "legendary jazz musician". This reputation will be helped by the fact that he was white, rather than black, as were most respected jazz musicians of the time.^[180]
• Henry Cowell founds the quarterly periodical New Music, which helped expose, introduce and organize European and Russian music to American composers.^[85]
• Jerome Kern's musical Show Boat is a "watershed (that leaves) earlier, more loosely constructed musicals far behind".^[26] Its major innovation is in using a well-developed plot, based on a novel by Edna Ferber, rather than appealing primarily in showy dancing, sets and catchy songs.

The radio industry matures, beginning to more successfully focus on increasing market share rather than "abstract cultural good", diminishing the "demand for fine-art music and correspondingly (increasing) the demand for popular music".[59] Big band swing music makes jazz a part of mainstream American pop. The popularity of swing ensembles inspires many jazz enthusiasts to focus on the improvisation and innovation, rather than the danceable pop sound of swing. This is the first form of popular music to be divided into separate realms of commercial and artistic success.[353] A number of jazz music journals also begin documenting the burgeoning genre of swing.[256] Early record companies specializing in jazz appear, like Commodore HRS and Blue Note, as do the first of a steady stream of American books on jazz, including Frederic Ramsey and Charles E. Smith's Jazzman, Wilder Hobson's American Jazz Music and Henry Osgood's So This Is Jazz.[316] Chicago becomes a "center for blues performance" in the city's large African-American community,[354] while a kind of piano-based blues called boogie-woogie becomes the most popular form of the blues.[10] The Golden Gate Quartet becomes one of the most popular recording artists in the country, beginning the era of greatest popularity for gospel music.[355] The term gospel comes to be applied to the genre now known as gospel music.[356] Greenwich Village becomes a center for a burgeoning American folk music revival, and is home to renowned performers like Aunt Molly Jackson, Sarah Ogan and Jim Garland.[357] The Hollywood musical settles on a format based around a "romantic comedy" with "four or five songs and a dance or two".[358] The town of Lindsborg, Kansas begins holding public celebrations of Swedish culture; the town will become a center for Swedish American music later in the century.[96] The piano accordion reaches its height of popularity, with many schools teaching the instrument and its repertoire, which depends in large part on Italian-derived music.[201] The bands of Lu Watters, Eddie Condon and Bob Crosby become popular in New York City, inspiring a revival of interest in old-time New Orleans-style jazz that will peak at the end of the following decade.[359] Sholom Secunda, a Yiddish theatre composer writes "Bay mir bist du sheyn", which becomes an unprecedented mainstream success.[298] Sonny Terry, accompanying Blind Boy Fuller, popularizes the use of the harmonica in the blues.[360] The importance of the tres in the Cuban son peaks, while Arsenio Rodríguez enjoys the height of his popularity; Rodriguez' main innovation is to incorporate the mambo, which is introduced in Cuba in this same era.[361] The Wings Over Jordan Choir begins performing on radio, becoming one of the first major large choirs in gospel music.[362]

Late 1940s music trends

Record companies begin more fiercely competing for radio airtime.[405] The first radio stations aimed exclusively at black listeners begin in the South, especially Atlanta, Louisville, Memphis, Los Angeles, St. Louis, New Orleans, Nashville and Miami.[473] Paul Bigsby creates an electric guitar for Merle Travis, a country singer. Though the exact date is not known, it may be among the earliest solid body electric guitars.[260] Eddie Jefferson becomes the first prominent performer of vocalese, songs in which new vocal tracks are set to instrumental jazz recordings.[474][475][476] The "idea that music could have an essence separate from the way it sounded in performance", an idea long seen as exclusive to Western classical music, comes to be applied to jazz through performers like Charlie Parker, focusing on "creation and performance, in the manner of classical musicians letting reception take care of itself"[21] Many country performers begin experimenting with a pedal steel, a steel guitar on a stand set up so that the guitarist can change pitches and chords.[49] The Old Regular Baptists of Jesus Christ, a small sect in eastern Kentucky, move in large numbers to Indiana, Michigan and Ohio. They preserve traditional Christian music techniques derived from 18th century New England, such as the heterophonic performance of monophonic tunes and the lining out of hymns.[477] George Herzog sets up the Archives of Traditional Music at Indiana University, which will be the largest ethnographic archive in an American university.[209] Inspired by pioneer Bill Monroe and his band, a generation of younger prformers, many of them working-class and frequently migrants from rural areas to cities, form a number of important proto-bluegrass bands.[478] The technology behind electric loudspeakers and amplifiers begins progressing rapidly.[60] Gospel jubilee singing groups end their last period of great popularity within the field of African-American Christian music.[479] The genre now known as rock and roll begins to reach its breakthrough form.[480] The guitar becomes the most prominent instrument in the blues.[10] The nascent bebop jazz scene comes to include a number of defining cultural characteristics, including the "unfortunate fashionability of heroin", which was inspired, in large part, by the success of addict Charlie Parker, the use of African-American vernacular-derived slang, and criticism of the racial politics of the era.[124] The independent record labels that dominate the African-American music industry begin targeting the growing teenage demographic by signing performers from that age group. Jesse Stone and Dave Bartholomew are among the legendary talent scouts from this era.[370] Tony de la Rosa adds the drum set to the Tejano conjunto style, forever changing the genre's sound; he will later add amplification and the bass to the field.[199] German American bands begin performing in a manner influenced by swing and jazz.[13] Slovenian American dance bands, until now dominated entirely by the accordion, come to include banjo, string bass and drum set.[13] The accordion polka craze in the United States peaks.[13] The Holocaust has several effects on Jewish music in the United States, namely leading to a decline in Yiddish language music and a rise in cantors being trained at home rather than in Europe.[298] Turkish Armenian 'ud player Oudi Harrant moves to the United States, becoming one of the most popular Middle Eastern musicians in the country.[98] The Yale Collegium, though not the first of its kind, is the most influential in beginning the American collegium movement, and is an important early institution in American early music.[147] A series of country boogie hits - country songs with an uptempo beat – become popular, including recordings like Tennessee Ernie Ford's "Shot Gun Boogie" and "Blackberry Boogie".[481] The term hi-fi, referring to high fidelity, comes into use, associated with the spread of LPs.[482] Latin jazz musicians like Chano Pozo and Juan Tizol develop a style known as Cubop.[114]
