  • Effective use of the secondary dominant A7 (V7/ii) resolving to Dm7.
  • The melancholic Fm6 creates a chromatic subdominant color before returning to Cmaj7.
  • A clear modulation to Bb major is established through the Gm7 C7 Bbmaj7 ii-V-I progression.
  • The D7 G7 progression acts as a V/V leading to the dominant, setting up resolution to the tonic.

Improvisation Focus: Adaptive scale choices based on momentary tonality, emphasizing chord tones and guide tones.

Difficulty Rating: 4 (Advanced Intermediate). The piece demands navigating multiple secondary dominants, a strong temporary modulation, and chromatic harmonies.
