Harmonic Highlights:
- Extensive use of passing and altered diminished chords (e.g., G07/A, Ab07, G07/Ab) for chromatic voice leading and tension.
- Sophisticated modal interchange exemplified by
Dbm,Dbm/maj7,Dbm6, andDbmb6, suggesting a strong influence from the Ab melodic minor scale. - Advanced dominant harmony, including secondary dominants with altered extensions (
F7b9,F7b9#5) and backdoor dominants (Ab7b9). - Abrupt, distant modulations, such as the
Bm7chord followingF7b9#5in the key of Ab, creating significant harmonic tension.
Improvisation Focus: Navigating the various modes of the Melodic Minor scale.
Difficulty Rating: 5 (Advanced) - due to the frequent use of altered dominants, complex modal interchange, distant modulations, and rapid harmonic shifts.
