Harmonic Highlights

  • Utilizes a classic “line cliché” where a descending inner voice (C-B-Bb-A) creates movement and shifting dissonance over a static C minor tonic.
  • Employs functional minor ii-V-i cadences (Dm7b5 - G7b9 - Cm) to provide strong tonal resolutions and break the modal staticity.
  • The progression expands the standard minor blues into a 24-bar form, requiring elongated harmonic pacing and awareness of the extended phrase structure.

Improvisation Focus C Melodic Minor scale to effectively outline the shifting major 7th and major 6th intervals within the tonic minor environment.

Difficulty Rating 2/5: While the slow tempo and repetitive harmony are accessible for beginners, the 24-bar structure and “line cliché” require sophisticated phrasing to avoid melodic stagnation.
