Some more words of wisdom from fiddleologist Mark Wilson:
By the way, we should note that our understanding of British tradition isn’t so hot either. I’ve not been able to hear very much Scottish music proper that is bowed in the fashion of the older Cape Bretoners. Apparently the 19th century wreaked havoc on the “folk fiddling” in Scotland: either the Presbyterians burned your instrument or you were taught to “elevate” your playing by incorporating classical techniques. Insofar as I am aware, we do not possess a very reliable picture of the evolution of Irish fiddling either. Once again people don’t seem to be asking the proper questions.
