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) and alt (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.
