Harmonic Highlights:

  • Pervasive use of V7/ii (A7) resolving to Dm7, establishing a clear secondary dominant function within C major.
  • Consistent application of the ii-V-I progression (Dm7-G7-Cmaj7) as a foundational harmonic device.
  • Introduction of Dm7b5, forming a iiø7-V7 (Dm7b5-G7) sequence that resolves to Cmaj7, adding a sophisticated tension-release.

Improvisation Focus: Mixolydian scale for dominant chord resolution.

Difficulty Rating: 3 (Intermediate) It features functional harmony with secondary dominants and a passing minor ii-V, requiring solid understanding of mode changes.
