Harmonic Highlights:

  • Prominent use of bVIImaj7#11 and bVImaj7#11 chords (Abmaj7#11, Gbmaj7#11) introduces strong Lydian color and chromatic juxtaposition.
  • Extensive chromatic planing is evident through repetitive Maj7-Dominant7 pairs (Abmaj7-Bb7, Amaj7-B7), creating non-functional, side-slipping harmony.
  • The initial Gm7, F7, Ebmaj7, F7 section establishes a temporary V-I tonicization of Eb within the broader Bb context, contrasting with later abstract movements.
  • Frequent, rapid non-diatonic shifts and modulations move far beyond traditional functional harmony, showcasing an advanced harmonic language.

Improvisation Focus: Navigating complex chromaticism and applying appropriate Lydian and altered dominant scales for each rapidly changing chord.

Difficulty Rating: 5 (Advanced) - Frequent non-functional chromaticism and rapid chord changes demand sophisticated melodic and harmonic understanding.
