Watch the Descending Chromatics online guitar lesson by Brad Carlton from Chord Studies: Jazz Turnarounds Vol. 1
When you listen to this turnaround, take notice of the descending chromatic line that we have in the upper voice. At this point in the lesson, I'd like to give you an assignment: go back and play the previous progressions without the bass note. You'll find the voicings leaner sounding and they'll fit better in the mix if you're playing out (especially with a bass player).
