Jazz Roots

Though jazz and classic blues are really early twentieth-century black music innovations, certain characteristics found in jazz do have their roots in much earlier musical traditions. Call and response, improvisation, the appropriation and reinvention of elements from Western art music: black music in the twentieth-century has never held a monopoly on these musical practices. For instance, the era American historians call "antebellum" (roughly 1815-1861) holds much of interest to researchers looking for the deep roots of jazz.
