Watch the Tag Line Blues online guitar lesson by Matthieu Brandt from Modern Mountain Banjo: Clawhammer & Up-Picking
This song is a 24-bar non-modal blues in the key of C with the chords C7, F7, and G7. The tuning is double C, so CGCD with pedal string tuned to G.
We're playing all these lines clawhammer style, with drop thumbing and some effects like slides, hammer-ons, and pull-offs. There is no up picking in this tune, but I'm using some open string pull-offs. The approach I took is something a bass player or backup guitar player would play in a blues setting, combined with some fills higher up the neck. These fills generally sit in between whatever a vocalist would sing, mostly at the end of a 2 or 4 bar phrase.
