Harmonic Highlights
- Frequent iiø7-V7 progressions, notably Dm7b5-G7b9/G7 resolving to Cm7, establishing the C minor tonality.
- Secondary iiø7-V7 movement (Am7b5-D7#9/D7) targets Gm7 (the v chord), adding harmonic tension and temporary modulation.
- The bVI chord (Abmaj7) provides modal color, often approached chromatically or via the Am7b5.
Improvisation Focus C Harmonic Minor scale and its related modes for navigating iiø7-V7-i progressions.
Difficulty Rating 4 (Advanced Intermediate). It requires navigating numerous minor ii-V-i progressions, altered dominants, and temporary modulations within a minor key.
