We think we've cracked the library tour conundrum, with this idea! Here's a Storify about our library. If you're a trad musician, this shows you much of what you need to know. For the rest - look out for the trad music guide or the expert staff to assist you find what you're looking for!
Karen went to talk to Marie Fielding's fiddle students the other day. We talked about the library, and about hms.scot, too. It's a website with the dual purpose of sharing 22 newly digitized historic fiddle tunebooks, and listing another 200 collections together with commentary about the compilers and details of where to see copies. (HMS = Historical Music of Scotland.) And we reminded ourselves that there are all sorts of little clues about performance practice in these collections, from the wording on the title page, to commentary in the preface or alongside the tunes, or the kind of bassline or fiddle ornamentation supplied.
And the National Library of Scotland has uploaded more digitized collections onto their Digital Gallery website in the year since the hms.scot Bass Culture project ended, so do look there too.
