Listen to the intro and first 5 bars of the slow blues in G.

The use of the G9 chord going down step by step is a signature T-Bone way of opening up a song.
Note the changes in timing of the melody notes he would play on top of these chords.
You use your pinky to play the extra notes on top, making the chord 13th chords.
Approaching the chords from below by means of slides is another T-Bone-ism.

Another trademark chord trick is the one he would use in the last two bars before changing to the IV chord.
He creates tension by moving the 9th chord up and down 1/2 step.
This motion has to be followed by the bass player, or else it’ll sound really off.

After he’s done moving around with these chords, he ends the chord riffs by quickly playing the tonic of the last chord on the first string.
He then moves to the IV chord via the chord 1 fret above.

The end progression basically starts right after you come back to the I chord.
This is often called the ‘Stormy Monday’ chord progression.

It’s a sequence of minor 7th chords walking up and down the neck.

Jazz players will play different scales on every chord and really send you to all corners.
T-Bone mostly stuck to playing blues, smiling all the way through.
Some notes in the blues scale will sound off at some points.

And you have to be very careful throwing in standard riffs, because most of them will not fit.

If you wanna get into playing all the right scales on these chords,
be prepared to do some serious studying.
This type of playing falls outside of the scope of this course.
