'Lo, Bob Bolton---
Now then--ye might as well ask with regard to the Welsh leek--"from when to when"? Or the English rose, or the bald eagle, or the---etc....... The detailed history of the fiddle in Scotland hasn't been one of my avidly-studied subjects! Perhaps some more -informed mudcatter can fill in the detail. A couple of wee points, though; many are the old Scottish melodies which just couldn't be played on the pipes, which are limited in their scope--while being ideally suited to the tunes which have been written for them. I believe, too that in auld times the fiddle in Scotland was somewhat different from the present day item. Again, some more Knowledgeable mudcatter may enlighten both of us?
