Harmonic Highlights

  • Frequent modal interchange between F major and F minor, utilizing Fm7, Ab6, and Fmaj7 to blur the tonal center.
  • Non-functional chromatic parallelism, specifically the stepwise descending Major 7th chords (Fmaj7 to Ebmaj7) and the Gbmaj7#11 resolution to Fm7.
  • Deceptive dominant movements, such as the B13 tritone-related dominant resolving to an unexpected Dmaj7.
  • Brief incursions of functional harmony via ii-V-i cells in the relative minor (Dm), providing temporary structural stability amidst chromaticism.

Improvisation Focus Chord-tone targeting and Lydian modal applications over shifting Major 7th “Constant Structures.”

Difficulty Rating 4/5. The rapid transitions between unrelated keys and non-functional chromatic shifts require advanced harmonic visualization and quick mental transposition.
