Harmonic Highlights:

  • Employs clear ii-V-I progressions for the tonic G minor and its relative major, Bb major.
  • Features an extended tonicization of the iv chord (C minor) via Dm7b5-G7b9-Cm7.
  • Modulates to the dominant key of D major, establishing it with a ii-V-I (Bm7-Em7-A7-D6).
  • Utilizes chromatic diminished chords, such as C#07 resolving to Dmaj7, for sophisticated harmonic motion.

Improvisation Focus: Functional harmony and chord-scale relationships across multiple temporary key centers.

Difficulty Rating: 4 (Advanced Intermediate). Frequent modulations and sophisticated chromaticism require a strong grasp of functional harmony and chord-scale applications.
