Harmonic Highlights:
- The
G#07functions as a chromatic passing diminished chord (vii°7/ii), creating tension before resolving smoothly to theAm7(ii). - The
Cmaj7(IV) transitioning toCm7(iv) before resolving toGmaj7(I) provides a distinct minor plagal sound, characteristic of Berlin’s ballad writing. - Standard
ii-V-I(Am7-D7-Gmaj7) andV/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.
