Harmonic Highlights
- Establishes Db major (enharmonically C#) through clear ii-V-I progressions (Ebm7-Ab7-Dbmaj7), frequently modulating to the IV chord (Gbmaj7).
- Employs highly chromatic altered dominant chords (e.g., C7#5, Ab7#5, G7#5), often creating unexpected resolutions or brief tonal shifts.
- Features rapid sequences of ii-V changes that navigate through multiple key centers, demanding agile harmonic understanding.
Improvisation Focus Altered scale application over dominant chords.
Difficulty Rating 4 (Advanced) - The rapid modulations, numerous altered dominants, and complex ii-V sequences require sophisticated harmonic awareness and technical proficiency.
