Harmonic Highlights:
- Prominent minor ii-V-i progressions (Dm7b5 - G7b9 - Cm7) establish the C minor tonality.
- Brief tonicization of the relative major (Eb) via F7 - Bb7 - Eb6, showcasing a common minor key harmonic device.
- The F#07 functions as a passing diminished chord, providing chromatic tension before resolving to Eb6/G.
- Frequent use of Eb6 (bIII) and its inversion Eb6/G provides stable, melancholic resting points outside of the tonic.
Improvisation Focus: C Harmonic Minor scale (C, D, Eb, F, G, Ab, B).
Difficulty Rating: 3 (Intermediate). The chart combines standard minor ii-V-i with secondary dominants and diminished chords, requiring a good understanding of minor key harmony.
