- The progression utilizes a chromatic passing diminished chord (Ab°7) to bridge the iii (Am7) and ii (Gm7), creating smooth stepwise descending voice leading.
- A secondary ii-V (Cm7 – F7) effectively tonicizes the IV chord (Bbmaj7), a classic transition in American Songbook repertoire.
- The inclusion of the II7 chord (G7) serves as a secondary dominant, heightening tension before returning to the functional ii-V (Gm7 – C7) turnaround.
Improvisation Focus Guide tone navigation, specifically targeting the resolving 3rds and 7ths to outline the chromatic movement of the diminished and secondary dominant chords.
Difficulty Rating 2/5: The tune features predictable functional harmony and a slow harmonic rhythm, making it an accessible vehicle for practicing basic ii-V-I vocabulary and chromatic passing tones.
