Harmonic Highlights
- Frequent, rapid ii-V-I progressions drive constant modulations throughout the form, creating a sense of restless harmonic motion.
- The tune features a signature descending cycle of major third key centers (e.g., Ebmaj7 to Dbmaj7 to Bmaj7).
- Clever use of secondary dominants and borrowed chords facilitates smooth, yet complex, transitions between distant tonal areas.
Improvisation Focus Fluidly outlining chord tones and guide tones for each rapid ii-V progression, adapting to frequent key changes.
Difficulty Rating 5 (Advanced). The constant, non-diatonic modulations require exceptional harmonic agility and quick melodic adaptation.
