Harmonic Highlights

  • Employs a persistent minor i–V movement (Cm7 to G7b9) that establishes a somber C minor tonality despite the Eb major key center.
  • Utilizes a chromatic parallel descent (Cm7–Bm7–Bbm7) to bridge the relative minor tonality to the subdominant Ab major section.
  • Features a Dbmaj7#11 acting as a bVII modal interchange chord, providing a Lydian flavor before resolving to the tonic Eb6 via the primary dominant.
  • Navigates frequent minor ii–V–i sequences, requiring precise management of altered dominant tensions like the b9 and b13.

Improvisation Focus C Harmonic Minor over the G7b9 to emphasize the dark, tension-heavy resolutions within the minor cadences.

Difficulty Rating 3/5: Requires the ability to fluidly shift between relative minor and major centers while navigating chromatic passing chords.
