- The progression utilizes a ii-V in F (Gm7-C7) that resolves to F7 instead of Fmaj7, creating a secondary dominant chain leading to Bbmaj7.
- Extensive modal interchange occurs through the minor iv (Fm7) and bVII7 (Bb7) chords borrowed from C minor, providing the characteristic “sweet and sour” chromaticism.
- The bridge features a sudden modulation to the relative major of the parallel minor (Eb Major) via a chromatic ii-V (Abm7-Db7 to Ebmaj7).
- Functional ambiguity is created by shifting between C Major tonic stability and subdominant-prolonged sequences in the A sections.
Improvisation Focus Navigating modal interchange and the chromatic shift to Eb Major in the bridge.
Difficulty Rating 3/5: The tune requires navigating non-diatonic key centers and frequent major/minor parallel shifts while maintaining a melodic arc.
