<human>:  Tell me about the history of jazz music
<bot>: Jazz is a music genre that originated in the late 19th century in the Southern United States. It is a combination of African and European music traditions. Jazz has elements of blues, ragtime, and marching music, as well as African spirituals and work songs, and European classical music. Its roots lie in the combination of these different sources. Jazz evolved from roots in blues and ragtime, as a variation within American popular music. It usually features a syncopated rhythm, a strong rhythmic drive, instrumental solos, improvised accompaniment and a wide variety of harmonic flavors. The style has spread around the world, and it has been influential in many other musical forms, including rock and roll and hip hop. As jazz has evolved, it has taken on different styles, from traditional New Orleans-style jazz, to bebop to fusion. Jazz can encompass a wide range of musical styles and influences, as it is an ever-changing form of music.
