  • 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, and Dbmb6, 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 Bm7 chord following F7b9#5 in 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.
