Harmonic Highlights:
- Prominent use of a chromatic diminished chord (B07) as a passing tone leading to the ii chord (Cm7), adding sophisticated voice leading.
- The characteristic “parallel minor” sound with the Eb6 - Ebm6 progression, often followed by an Ab9 (IV-iv-bVII) for added color.
- A clear tonicization of C minor via a ii-V-i progression (Dm7-G7b9-Cm7), demonstrating temporary key changes within the form.
- Frequent deployment of altered dominant chords (G7b9, Bb7b9) to create strong tension and resolution leading to subsequent chords.
Improvisation Focus: Altered Scale (Super Locrian)
Difficulty Rating: 4 (Advanced Intermediate). The combination of chromatic passing diminished, parallel minor shifts, temporary minor tonicizations, and frequent altered dominants requires a solid understanding of advanced harmonic concepts for effective improvisation.
