Harmonic Highlights:
- Successive ii-V-I progressions frequently tonicize distantly related keys (e.g., Bb, Db, B minor), creating significant harmonic shifts.
- Employs altered dominants and extensions like
#11(Db7#11) andalt(F#7alt) to add color, tension, and facilitate modulations. - Features non-diatonic target chords, such as the ii-V-I in Db major (bVI) and B minor (bVII), constantly shifting the tonal center.
Improvisation Focus: Chord-scale approach, adapting to rapid key center changes.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent and distant modulations demand a strong command of harmony and chord-scale application.
