Harmonic Highlights:
- Prominent use of II-V progressions (e.g., Gm7-C7b9, Am7-D7b9) frequently featuring b9 alterations on dominant chords.
- Modal mixture is a key feature, exemplified by the tonicization of the IV chord (Bb6) followed by its parallel minor (Bbm6).
- Secondary dominants (e.g., G7 acting as V/C, F7 as V/Bb) create temporary shifts in tonicity, often with #5 alterations (F7#5).
- The
Am7b5 - D7b9sequence strongly implies a temporary tonicization of G minor, introducing minor II-V-i motion.
Improvisation Focus: Altered Scale (Super Locrian) over the prominent V7b9 chords.
Difficulty Rating: 4/5 - Requires navigation of frequent II-V changes, altered dominants, and modal mixture beyond basic diatonic understanding.
