Harmonic Highlights

  • Employs a standard ii-V of IV (Bbm7-Eb7 to Abmaj7) followed by a backdoor bVII7 (Db7) resolving back to the tonic or mediant.
  • Features an extended secondary dominant cycle (VI7-II7-V7-I) using C7, F7, and Bb7, which requires smooth voice leading through changing dominant qualities.
  • The bridge shifts the tonal center to the mediant minor (G minor) via a strong ii-V turnaround (Am7b5 to D7b9), demanding a transition to the G harmonic minor or altered scale.

Improvisation Focus Voice leading through secondary dominant cycles and functional ii-V-I progressions.

Difficulty Rating 3/5: The tune is moderate due to the frequent secondary dominants and the brief but essential modulation to the relative minor’s minor during the bridge.
