Jazz is considered an original American musical genre, and it is widely celebrated throughout the world today. But its roots are much more humble. In fact, its origins can be traced to the time of slavery in America when work songs were created in the form of “call and response.” Jazz as a music form emerged in the South during the early 1900s, and by that time it was greatly influenced by African dance and drumming, ragtime, brass marching bands and blues—which also arose in that region.
