Harmonic Highlights

  • The opening Abmaj7 to G7 (bVImaj7 to V7) utilizes modal interchange from C minor, creating a signature chromatic pull toward the tonic.
  • The progression employs a “minor ii-V to major I” (Dm7b5 - G7 - Cmaj7), providing a distinctive dark-to-light resolution.
  • The bridge features a chromatic descending sequence (F#m7b5 - Fm7 - Em7 - Ebdim7 - Dm7), requiring smooth voice leading through shifting tonal centers.
  • Modulation to Ebmaj7 (bIIImaj7) briefly shifts the harmonic focus to the relative major of the parallel minor.

Improvisation Focus

Modal Mixture (switching between C major and C natural minor scales to navigate the bVI and ii-V movements).

Difficulty Rating

3 (Intermediate). The performer must navigate frequent shifts between major and minor tonalities and handle the chromaticism of the bridge.
