Why I Stopped Practicing Scales
A worn-out copy of The Jazz Piano Book by Mark Levine always sat on my piano. It served as the bible for jazz beginners worldwide, but for a long time, it represented a wall I simply could not climb.
I studied that book like a student preparing for an entrance exam. I memorized the ii-V-I progressions in all keys exactly as the book commanded. I programmed dozens of scales, from Ionian to Altered, deeply into my fingers. Theoretically, my playing should have been perfect.
However, whenever I listened to recordings of my practice after work, I was overwhelmed with frustration. It was not jazz. It was merely a fast finger exercise. I was listing notes without meaning inside the safe fence of scales. There was no Bill Evans lyricism and no Herbie Hancock edge. There was only the anxiety of struggling not to play a wrong note.
Since Mark Levine could not have been wrong, I realized that my approach itself was the problem. I had been obsessing over the material—the specific notes to play. In reality, the essence of jazz is not the material, but the direction. The important thing is not listing notes, but where you arrive.
From that day on, I stopped my mechanical scale practice. Instead, I redefined improvisation as a journey to find a destination. I started an experiment based on three precise principles.
Guide Tones
Mark Levine emphasized the importance of voice leading countless times in his book. Notes should connect naturally like flowing water when chords change. Because I was blinded by flashy scales, I had missed this core concept. I decided to reset my goal points.
Before, I played whatever my hands wanted to do. From then on, I decided to step on the third or seventh without fail the moment the bar changed. These two notes, known as guide tones, determine the color of the chord. They are the target points possessing the strongest gravity.
I experimented with the standard Dm7-G7-Cmaj7 progression in the key of C major. For Dm7, I set the target as C, the seventh. When the chord changed to G7, I moved to the B right next to it, the third. Finally, for Cmaj7, I stayed firmly on B, which is the seventh.
Something amazing happened when I simply connected these three notes. A clear story emerged in my playing. Moving from C to B is a half-step difference, yet even without moving my fingers dazzlingly, a natural and inevitable path opened up. This was the smooth voice leading Mark Levine had written about.
Enclosure
Once the skeleton was in place, adding the flesh was easy through a technique called enclosure.
Simply hitting the destination note B was too honest and boring. I started to surround and tighten in on the target note from above and below instead of hitting it directly. These notes act like supporting characters setting the mood before the main character appears.
I made my own rule. If the target is B, I first play C, the note right above it in the scale. Then I touch Bb, a half-step below the target, and finally resolve to B.
The moment I pressed Bb was particularly thrilling. The black key is a foreign entity in the key of C major. The moment this unstable note resolved to the target a half-step above, the anxiety turned into a powerful pleasure of resolution. This delivered the sophisticated taste of jazz that could never be produced while trapped inside a scale.
Delayed Resolution
The last thing I modified was time, or rhythm.
I abandoned the obsession that I had to fill every bar with eighth notes. Just as a person who talks incessantly has no charm, a ceaseless stream of notes is just noise.
I tried delayed resolution by placing a rest on the first beat instead of playing the target note right away. I emptied the downbeat and hit the target on the offbeat, or "settled" on the second beat after circling around with an enclosure.
The tension provided by this short silence was immense. The audience waits for the resolution note to appear on the first beat. When I slightly betray that expectation before finally satisfying it, the music comes alive and breathes.
Conclusion
By the time I closed the bible on the piano, I had gained an important realization. While people often say there are no wrong notes in jazz, that proposition needs to be revised.
There are no wrong notes, but there are unintended notes.
Notes wandering on the scale without any purpose are just noise. However, if you set a clear target and decorate the surroundings with enclosures before using the empty space of rhythm to arrive at the decisive moment, every dissonance takes on a beautiful tension.
Now, I do not wander on the keys. I explore the path to detour most elegantly toward the destination. I have finally found the real jazz that the thick bible had been trying to show me between the countless sheets of music.
