 years later. So when you think of where jazz came from, it came from the streets of St. Louis, from New Orleans, and it was Black musicians who developed this music on the streets. But where the instruments come from, it came from the military bands that were so prevalent in those days. So when you think of the instrumentation that's in a lot of jazz, right, it's things like the saxophone, the trumpet, the drums. These were all classical instruments that were being used in military bands in this country at that time.
