Watch the Wrap Up online guitar lesson by Brad Carlton from Chord Studies: Evolving Progressions Vol. 1
Our last progression in this series is a I - ii - ♭VII - V in E. This is where you can hone your skills that you gleaned from the material thus far. Choke the chords before changing to get nice, clean and consistent changes. Listen to the ♭VII, and get that outside sound in your ear as well as how that V chord wants resolve back to the I. Good luck!
