- Establishes Db major tonic with clear I-V7-I movements.
- Employs chromatic passing diminished chords (e.g., D07) to lead into diatonic ii-V progressions.
- Features an extended section of rapidly moving, chromatically related dominant 7th chords (e.g., Gb7-G7, B7-C7, E7-F7), often implying tritone substitutions and requiring constant re-evaluation of tonal centers.
Improvisation Focus: Altered dominant scales and chromaticism to navigate rapid key changes.
Difficulty Rating: 5 (Advanced) Demands sophisticated understanding and execution over numerous temporary tonal centers and complex chromatic harmony.
