Harmonic Highlights

  • Chromatic Minor 9th Planing: Features a striking, non-diatonic sequence of minor 9th chords (Em9, Bbm9, Am9, Ebm9) connected by chromatic tritone and half-step root movements, creating a “planar” or coloristic harmonic effect.
  • Chromatic Dominant & Modal Interchange: Incorporates a chromatic dominant (B7) creating tension before resolving to a modal mixture chord (Bbmaj7, bIII in G minor).
  • Modern ii-V Resolution: Utilizes an Am7 - D7#11 progression (ii-V) where the D7#11 (V7 with a Lydian Dominant quality) implies a sophisticated functional resolution to the G minor tonic.

Improvisation Focus Adapting melodic lines to the unique chromatic minor 9th planing.

Difficulty Rating 4 (Advanced Intermediate). The extensive chromaticism, non-functional harmony, and advanced chord extensions require sophisticated melodic and harmonic understanding.
