Harmonic Highlights:
- The early appearance of Ab7#11 (IV7 with Lydian Dominant quality) establishes sophisticated harmonic color.
- Frequent use of modal interchange is evident with Ebm7-Abm6, borrowing from the parallel minor.
- The chromatic sequence Gb7-B7-Bb7b13 showcases advanced dominant alterations and potential tritone substitutions.
- A clear iiø7-V7b9-i minor tonicization (Fm7b5-Bb7b9-Ebm7) adds significant harmonic tension and resolution.
Improvisation Focus: Applying the Altered Scale (Super Locrian) over dominant chords.
Difficulty Rating: 4. Its frequent use of modal interchange, altered dominants, and complex chromatic movements requires sophisticated harmonic understanding.
