Harmonic Highlights:
- Prominent use of modal interchange with Fm7b5-Bb7 (iiø7-V7) leading to Ebmaj7, importing a minor key color into a major resolution.
- The recurring F#07 functions as a common-tone diminished or a V7b9 substitution for D7, introducing chromatic tension to Gm7.
- Consistent application of Ab7 (IV7) injects a blues-inflected dominant sound, diverging from the diatonic Abmaj7.
Improvisation Focus: Navigating altered dominant functions and diminished scales.
Difficulty Rating: 3 (Intermediate) - The inclusion of modal interchange, common-tone diminished chords, and altered dominant voicings requires a solid grasp of extended harmonic concepts.
