Harmonic Highlights

  • Oscillating minor seventh chords (Dm7 to C#m7) utilize chromatic side-slipping to create modal ambiguity early in the form.
  • Sequential ii-V cells (F#m7-B7 to Em7-A7) showcase a cascading cycle of fifths that temporarily departs from the A minor tonic.
  • A diatonic stepwise descent (G, F, Em, Dm7, Cmaj7) provides a lyrical anchor against the more complex chromatic transitions.
  • The Bbmaj7#11 functions as a Lydian bII substitute, offering a sophisticated approach to the dominant before recycling through minor ii-V-i patterns.

Improvisation Focus Modal Interchange: Navigating the shifts between A Aeolian and A Melodic Minor while applying Lydian Dominant concepts over the non-functional ii-Vs.

Difficulty Rating 4/5. The rapid parallel chord movements and frequent modulation between secondary key centers require advanced harmonic fluency and quick mental transposition.
