Harmonic Highlights:
- The Ab07 (bIIIø7) serves as a chromatic passing diminished chord, elegantly leading to the Gm7 (ii).
- A brief tonicization of the mediant (Am7) is achieved through its secondary iiø7 chord, B07.
- The progression Am7 -> Ab7 -> Dmaj7 presents a highly chromatic and unexpected resolution, moving from the diatonic iii to a bVI7 then to a non-functional VImaj7.
- A clear modulation to the subdominant (Bbmaj7) is established via the classic ii-V-I progression of Cm7 - F7b9 - Bbmaj7.
Improvisation Focus: Navigating chromatic movements by precisely targeting chord tones and outlining secondary dominant/diminished functions.
Difficulty Rating: 5 (Advanced) - The piece presents complex, non-functional harmonic movements and frequent modulations that require precise melodic navigation and a deep understanding of advanced jazz harmony.
