Harmonic Highlights

  • Utilizes the subdominant minor (Abm6) to create a sophisticated, “dark” resolution typical of Great American Songbook ballads.
  • Employs a chromatic descending bridge via the Gbdim7, which acts as a passing chord between the Gm7 (iii) and Fm7 (ii).
  • Features secondary ii-V progressions (Am7b5–D7) to tonicize the iii chord (Gm7) and brief side-slipping dominant cycles (F#m7–B13 moving to Fm7–Bb13).

Improvisation Focus Eb Major/Bebop scale with G Harmonic Minor shifts for the D7 secondary dominant.

Difficulty Rating 3 - The tune’s predictable AABA form is balanced by frequent secondary dominants and chromatic shifts that require precise voice-leading.
