Harmonic Highlights:
- The
C07functions as a common-tone diminished (C#°7 enharmonically) leading to the ii chord, creating chromatic tension. - Modal interchange is prominent with the
Cm7chord, temporarily borrowing from the parallel minor mode to add color. - Multiple
iiø7-V7b9progressions are present, featuring altered dominants and secondary dominant functions. - The
Ab9leading toG7b9introduces chromatic dominant movement, acting as a tritone substitute or bVI7 resolving to V7.
Improvisation Focus: Navigating altered dominant chord tones and their extensions using melodic minor modes.
Difficulty Rating: 4 (Advanced Intermediate). The frequent use of altered dominants, borrowed chords, and passing diminished chords requires careful harmonic awareness and technical precision.
