Harmonic Highlights:
- Prominent V7b9-i resolution (G7b9 to Cm7) firmly establishing the C minor tonality.
- Extensive secondary dominant usage, notably D7b9 leading to Gm7 (V7/v - v), expanding harmonic movement.
- Chromatic harmonic devices, including tritone substitutions (Db7 for G7) and a common-tone diminished chord (Eb07 to Ebmaj7), add color and tension.
Improvisation Focus: Altered dominant scales.
Difficulty Rating: 4 (Advanced). The frequent altered dominant chords, tritone substitutions, and diminished harmony demand sophisticated harmonic understanding and scale application.
