“I teach Texas Style or 'contest style' fiddling. Most of my fiddlers jam quite often and almost all also play guitar. I am not sure my kids would fit into the bluegrass perspective.”
From what you say, not many of your students might find this class “for them”. But it’s also true that being able to “fake” solos and do tasteful backup on songs that come up at a jam is a skill that some “contest style” fiddlers might want to add. This skill is less about well-practiced technique than just getting out in a bluegrass situation and “learning how to play shortstop” where, while there are ground rules, no one really knows just what’s going to happen. Depending on what sort of jamming experience a student has had or wants, this kind of opportunity might be helpful.
