Harmonic Highlights

  • Frequent use of the bVII9 chord (B9) as a neighbor tone to the I major tonic, creating a distinct Lydian b7 harmonic flavor and subdominant minor substitution.
  • Chromatic and diatonic planning through the verse (Ebm7–Abm7) followed by tritone substitutions (D13#11) to resolve into the iii chord (Fm7).
  • Rapid shifts between major and minor tonalities, specifically utilizing minor ii-V-i progressions (Gm7b5–C7–Fm6) that disrupt the C# major home key.

Difficulty Rating

5/5. The lack of a repeating AABA structure combined with dense, non-functional chromaticism makes this one of the most challenging ballads in the jazz repertoire.
