Harmonic Highlights

  • Frequent use of slash chords and non-functional bass movement (e.g., Bbmaj7#11/A) creates ambiguous tonal foundations that prioritize texture over traditional cadences.
  • Abrupt chromatic shifts, such as Em9 to Bb7#5#9 to Ebm9, utilize tritone-related root movements and side-slipping to bypass standard ii-V logic.
  • Diminished chords (G°7, A#°7) function as chromatic connectors or leading-tone substitutes to stabilize the B minor center amidst surrounding non-diatonicism.
  • The final sequence of Major 7#11 chords provides a lush resolution, utilizing a cycle-of-fifths movement that tonicizes the home key through Lydian colors.

Improvisation Focus Modal tracking through shifting Lydian and Melodic Minor scales to accommodate the constant changes in tonal centers.

Difficulty Rating 5/5: The non-functional root movements, specific upper-structure tensions, and rapid modulations require advanced harmonic ears and precise linear control.
