I’ve known the tune Shady Grove for a long time. It’s well known, and has been recorded a zillion times. On the banjo, this is usually played in Sawmill tuning, or “mountain modal” tuning as it is also called. Here’s a fairly typical approach to the tune (and a beautiful one too!), played by Doc Watson and the Kruger Brothers.
More recently I’ve learned about another version of Shady Grove – played in a major rather than minor scale. This version is apparenty based on a version played by the late great NC autoharp player, Kilby Snow. Here is a performance of the major scale version posted by tripharmonica on YouTube.
I’ve recently learned a similar version on clawhammer banjo. It’s a lot of fun to play.
