Harmonic Highlights

  • Employs an extended circle-of-fifths turnaround (ii-V-iii-VI) in the opening bars, creating sophisticated diatonic tension before resolving to the tonic.
  • Features a minor ii-V (Em7b5-A7b9) functioning as a secondary transition to the supertonic (Dm7).
  • Utilizes the “backdoor” ii-V sequence (Fm7-Bb7) to provide a subdominant minor resolution back to Cmaj7.
  • Integrates tonicization of the IV chord (Gm7-C7 to Fmaj7), common in ABAC standards to provide harmonic variety.

Improvisation Focus Mastery of the minor ii-V-i vocabulary, specifically focusing on the Harmonic Minor scale over the dominant 7b9 chords.

Difficulty Rating 3/5: The tune remains in C major but requires the player to navigate frequent secondary ii-Vs and modal interchange smoothly.
