Harmonic Highlights

  • The composition utilizes modal interchange, transitioning from a somber C minor (parallel minor) to a bright C major (parallel major) to mirror the lyrical narrative.
  • The minor section relies on a repetitive ii-V cycle (Dm7b5 to G7b13), where the b13 provides the crucial functional tension characteristic of minor-key harmony.
  • The harmonic rhythm is relatively static, with the Cm6 tonic occupying multiple bars, requiring vertical awareness over the tonic minor before the dominant pivot to the major section.
  1. Improvisation Focus The C Melodic Minor scale provides the most cohesive melodic framework for the Cm6 and Dm7b5 segments.

  2. Difficulty Rating 2/5; the progression is repetitive and diatonic within its two tonal centers, making the shift between parallel keys the only significant conceptual hurdle.
