Harmonic Highlights:
- Frequent use of the minor iiø7-V7b9-i cadence (Dm7b5-G7b9-Cm) consistently establishes the C minor tonic.
- A striking shift to Cmaj7 introduces a parallel major tonic, providing significant harmonic contrast and brightness.
- A clear secondary dominant progression (Gm7-C7-Fmaj7) signals a temporary modulation to F major.
- The Bb7 chord functions as a dominant leading to related keys or a tritone substitution, enriching the harmonic movement.
Improvisation Focus: Navigating the C Harmonic Minor scale and its derived modes over the altered dominant and minor tonic chords.
Difficulty Rating: 3 (Intermediate). The blend of minor key harmony, altered dominants, and temporary modulations to parallel and related major keys requires solid harmonic understanding.
