Watch the T-Bone's Weather Report online guitar lesson by David Blacker from Swing Blues Survival Guide: Rhythm

We'll start off here with the "T-Bone 9th" shape, built off the A, D, G & B strings. We also covered this 9th chord shape in "T-Bone's Choice Cuts." It's such a great movable chord shape, and if you use your first finger to dampen the low E string and pinky to dampen the high E string, you can strum the entire guitar when playing it. Our IV chord is a C9 with a G in the bass.

T-Bone pretty much always plays his 9th chords with the 5 in the bass. You can strum the entire guitar with these chords too. When you approach the half-step movement over the I chord, it really helps to break it up into 3 different parts, as I demonstrate in the video breakdown. Over the IV and V chords it's nice to occasionally rake down the stings or arpeggiate the chords, two very characteristic T-Bone-isms.
