- The progression frequently pivots from the relative major (Ebmaj7) using a secondary dominant (C7) to lead to the iv minor (Fm7).
- The C7#9 chord, functioning as V7/Fm, introduces a blues-tinged #9 tension before resolving to Fm7.
- The fundamental Dm7b5 - G7 - Cm7 ii-V-i progression firmly grounds the C minor key center.
- A surprising Cmaj7 briefly appears after Bb7, suggesting a Picardy third or temporary major tonic, before immediately reverting to the minor ii-V of C minor.
Improvisation Focus: C Harmonic Minor scale.
Difficulty Rating: 4 (Advanced Intermediate). The combination of minor ii-V-i progressions, secondary dominants with extensions, and unexpected major tonic interpolations requires precise harmonic navigation.
