You were asking about teaching folk music in a group of 30 or more. I teach fiddle in a group setting, although never that many. However, in principle, what I have found works is to get the more advanced students to teach the beginners. Now, I don't know if that is useful in your context but it does work. You act as a kind of facilitator, moving from group to group, seeing how they are all doing and helping out here and there.

Is that of any use?

I would appreciate being in contact with other people who are doing the same thing as I am. My email address is lbeck@auroranet.nt.ca
