Harmonic Highlights:

  • The G#07 functions as a chromatic passing diminished chord (vii°7/ii), creating tension before resolving smoothly to the Am7 (ii).
  • The Cmaj7 (IV) transitioning to Cm7 (iv) before resolving to Gmaj7 (I) provides a distinct minor plagal sound, characteristic of Berlin’s ballad writing.
  • Standard ii-V-I (Am7-D7-Gmaj7) and V/V (A7) progressions are used, maintaining a clear functional harmony within the subtle chromaticism.

Improvisation Focus: G Major tonality, with specific attention to the iv minor and vii°7/ii alterations.

Difficulty Rating: 3. The use of chromatic passing diminished and minor plagal resolutions requires navigating beyond simple diatonicism.
