  By the lots of scot-irish did migrate to Canada, Australia and new Zealand and did take their music forms with them, did they create some new music form that i do not know of in those countries? If not, why in America and only in the south where black were? This tells me they took the alien music forms of black and intergrated them in the music they came with from europe to create the white american music forms. I believe that's what happened.  Any Scots-Irish who immigrated to other areas of the US or countries like Canada and Australia were in much much smaller numbers than in the US south. Most of them quickly became assimilated into the local Anglo culture. But the majority of Scots Irish immigrants came to the American south, particularly the Appalachian and Ozark regions. Up in the hills, and out in the back country of Appalachia and the Ozarks they were very isolated from the Anglo American mainstream culture. This isolation was like an incubator for their unique musical styles and culture to develop. It had nothing to do with Blacks, as I pointed out the hillfolk had nothing to do with Blacks, they were too poor to own slaves, and they were and most of them still are very racist people. The scots Irish hillbillies rednecks were playing their bluegrass, folk, country, and very rock n' roll 'ish' sounding music long before the Blacks were ever freed from slavery, and even after they were freed from slavery the hillfolk had little if any contact with Blacks. Blacks had no influence on indigenous White southern/Scots Irish music. Now remember Scots-Irish are not actual Irish, nor are they traditonal Scots, they are Scottish blooded people who had immigrated to northern Ireland, and so culturally they were a Scottish-Irish hybrid culture. Irish and Scottish are not the same as Scots-Irish/Ulster Scotts.
