Harmonic Highlights

  • Employs modal interchange by oscillating between a dark C minor tonality (i-iv-V) and a bright C major resolution (Imaj7).
  • Utilizes minor ii-V-i progressions (Dm7b5 - G7b13 - Cm6) where the altered dominant tension provides a sophisticated, pre-bop harmonic pull.
  • Incorporates the tonic minor 6th (Cm6) to establish a Melodic Minor or Dorian color, avoiding the instability of a minor 7th chord.

Improvisation Focus Parallel Key Switching: Master the transition between C Melodic Minor (for the minor sections) and C Ionian (for the major resolutions).

Difficulty Rating 3/5: The challenge lies in smoothly navigating the transition between parallel minor and major modes while managing altered dominant extensions.
