Watch the From Sus to Dom online guitar lesson by Brad Carlton from Chord Studies: Slow Blues Progressions Vol. 1
This is more of an urban style slow blues in which the bass line is E, D and A. On each chord we'll utilize two types of chords to compose our harmony. We start with the 9 sus 4 chord and then transition into a dominant seventh chord over each bass note. Try to keep your index finger free as you work through each cycle of chords so that you can easily barre when needed with minimal movement.
