1. What were the beginnings of music in America that developed into jazz?
2. In which city did jazz take hold? Why?
During the Slave trading days, New Orleans was a major slave-trading center, and near the slave markets were establishments that jazz took hold. Jazz initially had the reputation of low class (ie prostitute, and others of ill repute), so it suffered for a long time before it was accepted. Even Scott Joplin with his brillant rag-time music suffered from this bias. After the Civil War, New York developed a music scene, but it again was in establishments that sunday school ladies didn't frequent.
Here is an excellent site on the history of jazz.
