Harmonic Highlights

  • Utilizes chromatic descending diminished passing chords (D#m7 - D°7 - C#m7) to provide smooth voice-leading transitions between functional ii-V sequences.
  • Features rapid tonicization of distal keys, specifically shifting from the G# minor center to D# major via the ii-V (Fm7 - Bb7) progression.
  • Employs altered secondary dominants (G#7#5) and suspended dominants (F#7sus, C7sus) to create sophisticated harmonic tension and delay resolution.

Improvisation Focus Targeting guide-tone resolutions (3rds and 7ths) to maintain melodic continuity across frequent and rapid key shifts.

Difficulty Rating 4/5: The combination of an unusual primary key, dense harmonic rhythm, and constant modulations requires advanced harmonic navigation and mental agility.
