In case anyone is interested - I have added another section, Section VI (Manuscript Sources) Part 4 to my Corbetta web pages (if it has worked properly). It is about the two manuscripts in the Biblioteca Estense in Modena. Although they only include music from Corbetta's printed books they are actually quite interesting. I have updated the list of contents too. Comments and corrections welcome, preferably off the list.
You will find them at www.monicahall.co.uk/corbetta if you are lucky. Have a nice weekend. Monica To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
