- Parallel Chromatic Descent: The sequence Am7 – Abmaj7 – Gmaj7 – Gbm7 – Fmaj7 utilizes “constant structure” motion, replacing traditional diatonic cycles with sophisticated chromatic side-slipping.
- Functional Distortion: While rooted in F “Rhythm Changes,” the progression obscures the standard I-vi-ii-V via non-functional major seventh chords and delayed resolutions.
- Diminished Passing: The use of F#o7 acts as a vii°/ii, providing a sharp, diminished pivot to Gm7 that enhances the tension within the turnaround.
- Tritone Proximity: Frequent movement between chords a semitone apart forces a linear rather than cyclical harmonic perspective.
Improvisation Focus Linear chromaticism and “long-meter” phrasing to navigate the shifting non-diatonic planes.
Difficulty Rating 5 (Advanced). The relentless tempo combined with non-functional chromatic shifts requires exceptional technical facility and a highly developed ear for voice leading.
