Harmonic Highlights:

  • Utilizes a recurring I-VI-ii-V cycle where the C7 acts as a secondary dominant (V/ii), creating a strong functional pull toward the supertonic.
  • Employs a chromatic chain of altered dominants (G7b9 to C7b9) that functions as a III-VI-ii sequence, adding harmonic tension before resolving to the tonic.
  • Features a “backdoor” flavor or subdominant variation via the Ab7, which provides a bluesy contrast to the otherwise diatonic Eb major landscape.

Improvisation Focus: Navigating secondary dominants by targeting the 3rds and 7ths to highlight the temporary shifts away from the Eb major scale.

Difficulty Rating: 2/5: The tune relies on foundational jazz turnarounds and predictable harmonic cycles, making it an accessible entry point for learning standard song forms.
