- The progression employs a chromatic descent via tritone substitution (Am7 to Ab7) to pivot effectively from the F major tonic into the distant key of Db major.
- It utilizes rapid ii-V-I cells in both the tonic (F) and the flat-VI (Db), demanding quick mental transposition during the bridge.
- Altered dominant extensions (A7alt, D7b9) are used to create high-tension resolutions back to the primary ii-V (Gm7–C7) of the home key.
Improvisation Focus Navigating the abrupt modulation between the F Major and Db Major tonal centers using voice-led guide tones.
Difficulty Rating 3/5: The 3/4 waltz feel and the shift to the chromatic mediant key (Db) require intermediate harmonic fluency beyond basic diatonic standards.
