Watch the Nashville Shuffle online guitar lesson by Joe Dalton from 50 Country Guitar Licks You MUST Know
Speaking of Nashville shuffles, here's a descending chordal lick that's easy to place. It works over the transition from the 5 chord to the 1 chord. I use pick and fingers. Don't be afraid to slide here and there. On slower songs you may hear this kind of thing from the lap steel on Hank Williams Sr songs.
