Harmonic Highlights:

  • Frequent deployment of the minor-major 7th chord (Cm/maj7), establishing a poignant, sophisticated tonic sound.
  • Strong resolution using the iiø7-V7b9 (Dm7b5-G7b9) progression, clearly affirming the C minor key center.
  • Characteristic descending chromatic bass motion (C - B - Bb - A) underpinning various C minor voicings (e.g., Cm6, Cm/maj7/B, Cm7/Bb, Cm6/A).
  • The F7 chord, acting as a bIII7 or V/Bb, momentarily introduces dominant tension before returning to the tonic complex.

Improvisation Focus: C Harmonic Minor scale.

Difficulty Rating: 4 (Advanced Intermediate) - The blend of minor-major 7 chords, chromatic basslines, and frequent dominant extensions requires nuanced harmonic understanding.
