Harmonic Highlights

  • Frequent chromatic mediant relationships, utilizing Maj7 chords (e.g., Bbmaj7, Abmaj7, Dbmaj7) that shift outside diatonic expectations.
  • Strategic application of bIIIMaj7#11 (Ebmaj7#11) often preceding minor chords, indicating both modal interchange and tritone substitution.
  • Consistent use of extended harmonies, especially the #11, imbues many chords (Ebmaj7#11, Dmaj7#11) with a characteristic open, floating sound.

Improvisation Focus Navigating rapid, non-diatonic key center shifts and modal interchange, requiring flexible mode application.

Difficulty Rating 5 (Advanced) - The complex, chromatically shifting harmonies, frequent modal interchange, and extended chord voicings demand a sophisticated harmonic understanding.
