Watch the Country Shuffle Solo online guitar lesson by Jason Loughlin from Essentials: Country Soloing Styles
The solo kicks off with a typical steel guitar pickup that pedals off of the low G. I establish a motif that always ends with a diatonic step from above approach to the chord tone. Then, I use my C augmented 7th arpeggio to setup the IV chord. To lead the IV into the V, I arpeggiate the F triad and chromatically walk it into G. Over the G chord, I can use a V chord sub, which is D7. So, I'm going to sub in a D7 over the G and resolve back to G.
For the next chorus, I start with another classic steel pickup. This time it's a contrary motion lick. I have two voices moving in opposite directions. Next, I use double stops and bring out the bouncy rhythm associated with shuffles. When I get to my IV chord, I use the IV sub. My IV is F, so I have to think what is the IV chord of F. It's Bb major. So, on the downbeat of the F chord, I play a Bb major triad and resolve to an F major triad. Then, I use an F# diminished triad to imply an altered D7 leading into G. When I get to the G chord, I use a classic arpeggio pattern with an approach note and end with a bluesy lick over the I chord.
