Harmonic Highlights

  • Employs a minor line clichĂ© (Bbm–Bbm/maj7–Bbm7–Bbm6) to establish a haunting, descending chromatic inner voice within the tonic.
  • Features abrupt, non-diatonic shifts to chords like F#m7, creating a surreal, “out-of-key” tension that bypasses traditional functional harmony.
  • Utilizes highly altered dominant 7th chords (C7#9, F7#9) to provide dense, dark tension before resolving back to the Bb minor center.
  • Integrates subdominant minor variations (Ebm7 to Ebm7b5) to expand the harmonic palette and reinforce the melancholy mood.

Improvisation Focus The Melodic Minor scale and its modes, specifically the Altered scale over V7 chords and the tonic minor-major sound.

Difficulty Rating 5/5: The dense chromaticism, non-functional harmonic leaps, and slow, exposed tempo demand extreme harmonic precision and sophisticated melodic phrasing.
