Harmonic Highlights:

  • Features a repeating descending ii-V-I progression by whole step (Dmaj7, Cmaj7, Bbmaj7).
  • Each ii-V-I resolves to a major seven tonic, establishing distinct temporary key centers.
  • The modulation from one ii-V-I to the next is a whole step descent from the previous tonic, e.g., Dmaj7 to the start of the C major ii-V.
  • This cyclical, predictable modulation defines the entire harmonic movement.

Improvisation Focus: Directly outlining chord tones and appropriate scales (Dorian, Mixolydian, Lydian) for each rapidly changing ii-V-I progression.

Difficulty Rating: 4 (Advanced Intermediate) - Requires agile navigation through rapid, cyclically modulating ii-V-I sequences across multiple temporary key centers.
