Harmonic Highlights:
- Chromatic ii-V-I Modulations: Features a prominent F#m7-B7-Emaj7 progression, a striking modulation to E major (a tritone from the tonic Eb), creating a sophisticated harmonic departure.
- Extensive Use of Altered Dominants and Tritone Substitutions: Employs chords like Bb7b13, Ab7alt, and D7 (as a tritone substitute for Ab7) to add tension and unexpected resolutions.
- Non-Diatonic Major 7 Chords: Integrates bVImaj7 (Dbmaj7) and bIIImaj7 (Gbmaj7) within the Eb minor context, alongside sudden chromatic shifts like Em7, enriching the harmony beyond typical minor keys.
Improvisation Focus: Chord-scale flexibility, particularly altered scales and navigating transient modulations.
Difficulty Rating: 5 (Advanced) - The complex modulations, extensive use of altered dominants, and non-diatonic chord movements demand a high level of harmonic sophistication.
