- The progression utilizes Gm7b5–C7b9 (minor ii–V) resolving to Fmaj7, employing modal interchange to add “dark” harmonic color to a major tonic resolution.
- A chromatic passing motion occurs via Am7–Ab°7–Gm7, where the diminished chord facilitates a smooth voice-leading descent to the supertonic.
- The bridge shifts to the mediant key (A minor) using a Bm7b5–E7b9 (ii–V of iii) sequence, requiring a temporary adjustment of the tonal center.
- The Eb7#11 functions as a “back-door” dominant (bVII7), providing a characteristic jazz resolution back to the Fmaj7 tonic.
Improvisation Focus Navigating minor ii–V–I guide tones, specifically targeting the b5 and b9 tensions to resolve cleanly into major tonic chord tones.
Difficulty Rating 3/5: The tune is accessible but requires precision when managing alternating major/minor ii–V colors and the brief modulation to the mediant.
