Solo in thumb position like a horn player.

We seldom truly shift in thumb position — we pivot. The second and third fingers stay planted as pivot points while the thumb and first finger move a half- or whole-step to catch the next note. Knowing where you can pivot at any moment is what makes playing over changes easy.

Demonstrated through the etude on Coltrane's "Moments Notice" and the "Pivot Finger" etude — with 62 worked pivoting examples across first position in the PDF packet.

Thumb position is a series of positions, not one position with a couple of extra notes. We break free of the "Tetris block" by using the thumb as a capo — resting it on the F♯, C♯, and G♯, not only on the harmonics. The relationship between the thumb and the third finger is what lets you move between positions cleanly.

Once you see how many notes that opens up, you stop retreating to the same comfortable shape every time.

The same thumb notes that extend thumb position also get you into it. We use them as a transitional tool from the lower and middle register, then fall naturally into first position on the harmonics. The key is to practice your scales as pathways, not key centers — spanning as much of the fingerboard as possible.

That's how you stop sounding like a player who's stuck once they arrive in thumb position, and start moving back and forth with fluency.

This is where it all pays off. The jazz language is mostly half-step voice leading, so if you know where the half-steps are, you know where to resolve. We work the Cherokee etude "Time to Burn" — shifting the thumb to meet each change, including the thumb on the G♭ to nail that Ab7 — then take on the harder bridge the same way.

You won't always play the changes one hundred percent, and that's fine. What makes it work is knowing exactly where to resolve.

Fourths feel impossible because the bass is tuned in fourths — but the fix starts with getting your elbow up so you can angle your hand. Then you use the thumb to play fourths all around the fingerboard instead of in one spot. We work the "Ornithology" melody, which is full of fourths and half-steps, with every fingering laid out in the PDF.

Once you realize it's possible, you stop being jealous of the saxophone players — you've got the fourth language too.

The technique is for a bigger purpose: making art. We use the 0-1-2 and 0-1-3 combinations to nail changes with precision on a hard progression, then loosen the reins — because when you're soloing, you're not responsible for the changes the way you are when you're walking.

Then we go outside: scales over a B♭ blues and an Eb7 (yes, even E harmonic minor over Eb7), practiced as pathways across the fingerboard so you have as many options as possible.

Sound comes last on purpose — the technique has to be in place first, because it's so nuanced it can get in the way of a good sound. The common mistake is forcing it: less string makes players dig in harder, which kills the tone and doesn't carry past ten or twenty feet.

The opposite is true. A light right hand and a delicate left hand give you a sound that's both more beautiful and bigger — up high and down low.
