  • Pervasive Modal Interchange: The consistent use of Cm6 as the primary tonic chord in a C major context establishes a strong C minor modal flavor, frequently borrowing from the parallel minor.
  • Dominant Resolution to Parallel Minor: The D7-G7 (V/V-V) progression repeatedly resolves to Cm6, directing the dominant function towards the parallel minor tonic.
  • Minor Subdominant Tonicization: A distinct Gm7b5-C7b9-Fm6 progression temporarily tonicizes F minor, the iv minor region.
  • Minor ii-V Functionality: The Dm7b5-G7 progression functions as a direct iiø7-V7 in C minor, further emphasizing the minor tonality.

Improvisation Focus: C Dorian mode and its melodic extensions.

Difficulty Rating: 4 (Advanced Intermediate). The constant modal interchange, frequent temporary minor key modulations, and altered dominants require a sophisticated harmonic understanding.
