Early Roots

Jazz originated in the late 19th and early 20th centuries in the United States, primarily in New Orleans. It emerged from a blend of African rhythms, European classical music, and the blues. The early jazz music was characterized by its improvisational nature, syncopated rhythms, and bluesy melodies.
