Harmonic Highlights

  • Employs a “backdoor” ii-V sequence (Fm7–Bb7) to resolve to the tonic, utilizing the bVII7 chord for a distinct modal interchange flavor.
  • Features a sudden shift to the bVI key center (Abmaj7) via a secondary ii-V (Bbm7–Eb7), breaking the primary C major tonality.
  • Utilizes a sequential ii-V chain (Am7–D7 to Dm7–G7) to create forward momentum back toward the home key.
  • Concludes with the iconic “Tadd Dameron Turnaround” (I–bIII–bVI–bII), replacing the standard I–vi–ii–V with a series of chromatically shifting major seventh chords.

Improvisation Focus Guide-tone voice leading to smoothly navigate the frequent non-diatonic ii-V resolutions and the final turnaround.

Difficulty Rating 3/5. The tune requires precise navigation of rapid key center shifts and a non-functional closing turnaround despite its short 16-bar form.
