Harmonic Highlights:
- The Ab07 (bIIIdim7) before Gm7 creates a strong chromatic tension, functioning as a passing diminished chord leading to the ii.
- A distinctive descending dominant chain is observed with F7 (V7/IV), Eb7 (bVII7), and D7 (V7/ii), introducing non-functional chromaticism and a bluesy color.
- The Bbm7-Eb7 ii-V progression directly establishes a temporary modulation to Ab major (bIII), providing a moment of contrasting key center.
Improvisation Focus: Navigating temporary modulations and chromatic passing chords using a precise chord-scale approach.
Difficulty Rating: 4 (Advanced Intermediate). The frequent chromatic alterations, non-standard dominant voicings, and sudden key center shifts demand strong harmonic awareness and agility.
