  • Harmonic Highlights

    • Prominent use of minor/major 7 chords (e.g., Bbm/maj7) establishes a distinctive, melancholic minor sound, distinct from typical natural or harmonic minor.
    • Frequent, sometimes chromatic, modulations (e.g., Eb minor to E major, then A major) create a constantly shifting tonal center.
    • Strategic deployment of ii-V-I progressions (F#m7-B7-Emaj7, Bm7-E7-Amaj7) anchors the rapid harmonic movement.
    • Chromatically descending minor tonalities (Bbm/maj7 to Abm/maj7) create a unique, introspective color.
  • Improvisation Focus Melodic minor scales for the m/maj7 chords and altered scales for dominant chords are paramount.

  • Difficulty Rating 5 (Advanced). The sophisticated harmony with rapid, non-diatonic modulations and complex chord qualities demands advanced harmonic knowledge and execution.
