- Chromatic Diminished Passing Chords: The use of Abº7 to bridge Am7 (iii) and Gm7 (ii) creates smooth, step-wise voice leading common in high-tier swing arrangements.
- Minor ii-V Interpolation: The Am7b5 to D7b13 sequence functions as a secondary turnaround, momentarily treating the Gm7 (ii) as a minor tonic for increased tension.
- Modal Interchange and Substitutions: The presence of Bbm6 (minor iv) and Eb7 (tritone substitution of V/V or backdoor bVII) adds sophisticated subdominant minor shading to the D minor/F major tonal center.
Improvisation Focus The F major bebop scale, utilizing chromatic passing tones to emphasize chord tones during the frequent iii-biio-ii-V-I progressions.
Difficulty Rating 3/5. The harmonic rhythm is predictable, but the frequent chromatic passing chords and minor-key ii-V insertions require intermediate-level precision in voice leading.
