Harmonic Highlights

  • Frequent tonicization of the subdominant minor (Cm) via a strong iiø-V7-i progression (Dm7b5-G7b9-Cm7).
  • Prominent use of secondary dominants, such as G7 (V7/Cm) and C7 (V7/F), creating strong forward motion and temporary modulations.
  • Resolves strongly to the relative major (Bbmaj7) through a definitive ii-V-I progression (Cm7-F7-Bbmaj7), highlighting the interplay between G minor and Bb major.

Improvisation Focus Navigating altered dominant scales for effective resolution over the numerous V7 chords.

Difficulty Rating 4 (Advanced Intermediate) - The continuous use of altered dominants and rapid key center shifts requires sophisticated harmonic awareness.
