I don't suppose you give lessons in the Fribourg area? That's a bit of a distance away from Fribourg I believe. (Just moved here, so still trying to find my bearings).
You wouldn't happen to know of any guitar teachers in Fribourg?
Yes, I'm afraid it is a bit far - about 3 hours I reckon.
I don't know any musicians outside of Basel/Zürich unfortunately.
However, there are loads of music schools around - I get the impression that not much instrumental tuition goes on in schools, hence lot's of private schools.
