Harmonic Highlights:
- Frequent use of altered dominants (e.g., Bb7#5, D7#5) creates significant harmonic tension.
- Prominent backdoor dominant progressions (Db7 resolving to Ebmaj7/Eb6) add a distinctive flavor.
- Temporary ii-V sequences (Gm7b5-C7) briefly tonicize F minor.
- The progression from Ebmaj7 to Eb7, then to Abm6-Db7, introduces a minor iv chord and a strong subdominant pull.
Improvisation Focus: The Altered Scale (Super Locrian) for navigating the dominant 7#5 chords.
Difficulty Rating: 4 (Advanced Intermediate) The blend of altered dominants, backdoor resolutions, and temporary modulations demands precise chord-scale application and harmonic awareness.
