Harmonic Highlights

  • The appearance of Eb7 following Gm7 functions as a “backdoor” dominant or a tritone substitution for the secondary dominant (A7), providing a chromatic bridge to the C7 dominant.
  • The progression utilizes frequent ii-V-I cells in F Major, often interrupted by secondary dominants like D7 (V/ii) to create a sense of forward motion and sophisticated voice leading.
  • The bridge shifts the tonal center via a ii-V (Bm7 - E7) to the mediant key of A minor, adding a poignant, temporary shift in mood characteristic of Rodgers and Hart ballads.

Improvisation Focus Navigating the F Major scale while emphasizing the Lydian Dominant (Eb7) and melodic minor (E7 to Am) shifts during non-diatonic transitions.

Difficulty Rating 3/5. The standard is melodically intuitive but requires a firm grasp of chromatic substitutions and a smooth transition into the mediant key during the bridge.
