I played a concert in Warsaw about eight years ago, playing lute songs with a soprano. I can't remember where in Warsaw it was. We also played about four other cities on a tour sponsored by the British Council. Very interesting place, Poland! The British Council Ambassador was Scottish and wore a kilt all the time. He was permanently drunk, and at one point left his jacket with our entire fee for the five concerts on a bench in the main square in Warsaw during an outdoor concert attended by a few hundered people. We went back there at 5am and found it where he had left it...
I have a lot of thinking to do about Sor's technique before I say any more. Rob To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
