  Blacks and whites were always segregated and never socialised. Black musical forms were almost created in a vacuum- devoid of white influence if any.  You have it backwards, White musical forms were created in a vacuum devoid of black influence. Blacks never ever went out into the Scots-Irish hillbilly territory in Appalachia and the Ozark region, or down in Lousiana in Cajun country. They had no contact with blacks to influence their music. But as for the Blacks being segregated, and never socializing, you don't need to hang out and socialize to hear music. They obviously heard some White country, bluegrass, folk, and classical, and honky tonk or boogie woogie (yes boogie is a White thing not a Black thang), music somewhere. Especially in New Orleans, the French Creoles tended to have much more relaxed attitudes towards Blacks than their Anglo/Celtic neighbors, you better believe Blacks had plenty of contact with White music in New Orleans, I wonder why jazz was born in N.O.? Just because they were segregated doesen't mean Blacks and Whites had zero contact. As I'm sure you realize Blacks were White man's servants and slaves and obviously got an earful of their music.OBVIOUSLY, or else there would never have been any blues or jazz. They didn't play that stuff or have those instruments in Africa y'know.....:rolleyes:    The slaves no doubt heard their masters and their guests having parties and playing fiddle music, square dance, folk, country, bluegrass, classical etc...... Blacks did not hardly create jazz or blues without any outside White influence, all the instruments they use are White instruments in the first place where did they get these instruments if they had ZERO contact with Whites?:rolleyes:(stole them?:D) Where did they learn to play them? There are several good posts on this thread that explain pretty good how the blues and jazz were influenced by White styles of music much much more than Rock N' Roll was ever influence by blues or any other supposed Black music. But whatever you think is true. If you wish to believe that all music on planet Earth originated with your primitive African ancestors then go right ahead, more power to ya.
