Harmonic Highlights

  • Employs a foundational I-vi-ii-V turnaround in Eb major, establishing a classic A-section stability common in Great American Songbook standards.
  • Integrates a secondary dominant (C7) to provide a stronger pull toward the ii (Fm7) chord, momentarily intensifying the subdominant resolution.
  • Features a prominent modulation to the mediant key of G major (III) via a functional ii-V-I sequence (Am7-D7-G6).
  • Utilizes a symmetrical harmonic structure where the G major section mirrors the initial Eb major movement, requiring clear navigation of distant tonal centers.

Improvisation Focus Voice-leading through the abrupt modulation from Eb major to G major using guide tones.

Difficulty Rating 2; the progression consists of predictable ii-V-I cells and clear key changes, making it accessible for intermediate players.
