Harmonic Highlights:
- The
Ab07(bII07) functions as a chromatic connector, often leading to Gm7 or replacing a V/ii chord, providing color between Fmaj7 and Gm7. - Features a clear tonicization of the subdominant, Bb major, through a
Cm7-F7-Bb6(ii-V-I in Bb) progression. - A notable descending chromatic dominant progression (
Bb7-A7-Ab7) introduces complex temporary modulations and requires quick harmonic adjustments.
Improvisation Focus: Utilizing altered scales for dominant 7th chords and diminished scales for diminished chords.
Difficulty Rating: 4 (Advanced Intermediate). The frequent chromatic diminished chords and the challenging descending chromatic dominant progression require advanced harmonic navigation.
