Jazz poetry is poetry that "demonstrates jazz-like rhythm or the feel of improvisation". During the 1920s, several poets began to eschew the conventions of rhythm and style; among these were Ezra Pound, T. S. Eliot, and E. E. Cummings. The significance of the simultaneous evolution of poetry and jazz during the 1920s was apparent to many poets of the era, resulting in the merging of the two art forms into jazz poetry. Jazz poetry has long been something of an "outsider" art form that exists somewhere outside the mainstream, having been conceived in the 1920s by African-Americans, maintained in the 1950s by counterculture poets like those of the Beat generation, and adapted in modern times into hip-hop music and live poetry events known as poetry slams.
Early jazz poetry did not mimic the sounds and improvisational spirit of jazz. Instead, it heavily referenced the musical form with allusions made to musicians, instruments, and locations key to the burgeoning jazz scene. Poets like Vachel Lindsay (who actually abhorred the "primitive" sound of jazz music) and Mina Loy wrote poetry in this vein. It was with the advent of the Harlem Renaissance that jazz poetry developed into what it is today.
Poets like Langston Hughes and Paul Lawrence Dunbar incorporated the syncopated rhythms and repetitive phrases of blues and jazz music into their writing. Hughes and Dunbar, like many Harlem Renaissance writers, were deeply concerned with racial pride and with the creation of purely African-American poetry. Since jazz music was an important part of African-American culture at the time, Hughes and others like him adapted the musical genre to create their own, singularly African-American voices that could easily be distinguished from the work of white poets. Many of Hughes' poems, such as "The Weary Blues," sound almost exactly like popular jazz and blues songs of the period, and vice versa. His work is also highly evocative of spirituals.
As members of the (largely white) Beat generation began to embrace aspects of African-American culture during the 1950s, the art of jazz poetry shifted its focus from racial pride and individuality to spontaneity and freedom. In this case, both jazz poetry and jazz music were seen as powerful statements against the status quo. Jack Kerouac would often accompany his readings of poetry with music, playing the piano
The tradition of jazz poetry has been carried on by hip-hop and rap artists, who often set poetic lyrics to syncopated beats. Another parallel that can be drawn is that of the freestyle rap, which features lyrics improvised to a beat, thus capturing the spontaneous, improvised nature of the jazz poem.
Spoken word, a genre made up of experimental text-based performance artists and poets, also emphasizes the relationship between poetry and performance, and can sometimes involve musical accompaniment and/or improvisation. Like jazz poetry, spoken word poetry de-emphasizes poetry's roots in academia and instead focuses on popular culture and issues of current social significance. One of spoken word's best-known forms, slam poetry, although it is usually memorized and not normally performed with music, often uses styles that owe a debt to jazz poetry.
