Harmonic Highlights:
- The Bbø7 chord functions as a chromatic common-tone diminished leading into Cmaj7, creating distinctive tension.
- A clear modal interchange occurs with Fm7 (iv) resolving to Cmaj7 (I), providing a characteristic melancholic color borrowed from the parallel minor.
- F7 (IV7) preceding Em7 (iii) suggests a tritone substitution for B7 (V7/iii), showcasing a chromatic dominant function.
- The progression Am7-D7-Gmaj7 clearly outlines a ii-V-I in G major, temporarily tonicizing the dominant key.
Improvisation Focus: Chord tones and their extensions.
Difficulty Rating: 3/5 (Intermediate). The blend of modal interchange, diminished chords, and secondary dominants requires an understanding of diverse harmonic functions beyond basic diatonicism.
