Harmonic Highlights

  • Extensive use of modal interchange, specifically the pivot from Gmaj7 to Cm7, transitioning the tonality from major to subdominant minor.
  • Chromatic descent and substitution patterns utilizing Eb7 to D7, functioning as a tritone-adjacent approach to the dominant.
  • Secondary ii-V-i motion (Bm7b5 - E7b9 - Am7) targeting the relative minor, providing a temporary tonal shift before returning to the tonic.
  • Introduction of Abmaj7 (bVI) acting as a subdominant minor variant, creating a plush, non-diatonic preparation for the final cadence.

Improvisation Focus Linear Chromaticism: Emphasizing smooth voice-leading across the major-to-minor modal shifts while utilizing Tristano’s signature rhythmic displacement.

Difficulty Rating 4/5: The frequent shifts into the subdominant minor and the reliance on precise chromatic voice-leading demand advanced harmonic awareness and rhythmic independence.
