Jazz is an American musical art form which originated in the beginning of the 20th century in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes, improvisation, polyrhythms, syncopation, and the swung note.

From its early development until the present, jazz has also incorporated music from 19th and 20th century American popular music. The word jazz began as a West Coast slang term of uncertain derivation and was first used to refer to music in Chicago in about 1915; for the origin and history, see Jazz (word).

Jazz has, from its early 20th century inception, spawned a variety of subgenres, from New Orleans Dixieland dating from the early 1910s, big band-style swing from the 1930s and 1940s, bebop from the mid-1940s, a variety of Latin jazz fusions such as Afro-Cuban and Brazilian jazz from the 1950s and 1960s, jazz-rock fusion from the 1970s and later developments such as acid jazz.

Origins

Ragtime

Main: Ragtime

Ragtime appeared as sheet music with the African American entertainer Ernest Hogan's hit songs in 1895, and two years later Vess Ossman recorded a medley of these songs as a banjo solo "Rag Time Medley". Also in 1897, the white composer William H. Krell published his "Mississippi Rag" as the first written piano instrumental ragtime piece. The classically-trained pianist Scott Joplin produced his "Original Rags" in the following year, then in 1899 had an international hit with "Maple Leaf Rag." He wrote numerous popular rags combining syncopation, banjo figurations and sometimes call-and-response, which led to the ragtime idiom being taken up by classical composers including Claude Debussy and Igor Stravinsky. Blues music was published and popularized by W. C. Handy, whose "Memphis Blues" of 1912 and "St. Louis Blues" of 1914 both became jazz standards.

New Orleans music

The Original Dixieland Jass Band's "Livery Stable Blues" released early in 1917 is one of the early jazz records. That year numerous other bands made recordings featuring "jazz" in the title or band name, mostly ragtime or novelty records rather than jazz. In September 1917 W.C. Handy's Orchestra of Memphis recorded a cover version of "Livery Stable Blues". In February 1918 James Reese Europe's "Hellfighters" infantry band took ragtime to Europe during World War I, then on return recorded Dixieland standards including "The Darktown Strutter's Ball".
