Now I've taught piano lessons for, like, twenty years, but I always refuse to teach saw lessons. It's not a magician-giving-away-her-secrets thing that keeps me from teaching saw. It's that it's really difficult for most people to even manage a squeak on the thing. When someone tries it and they can't make a sound, there's very little I can do to help them. I can tell you how to hold it, how to make the S-curve, and approximately where to bow on the steel, but I cannot help you with the "feel."
Basically, it's a lot trickier than it looks.
But feel free to give it a try. I play Stanley saws, and my favorite is the 26". When I'm abroad I settle for the 22" Stanley Fat Max because it's the longest I've ever been able to find (I only ever travel with a carry-on, and you can't carry-on a saw.)
Anyway, for your holiday pleasure, here's a little video I shot yesterday of me and the Great Steve Cooley playing "O Holy Night" on the banjo and saw. I always loved this melody, and when you're playing saw, it's all about the melody (not the bass -- sorry, couldn't resist).
