Harmonic Highlights

  • Employs a minor ii-V-i (Dm7b5 - G7b13 - Cm) as the primary structural engine, often preceded by a secondary ii-V (Am7b5 - D7) targeting the dominant G7.
  • The bridge modulates to the subdominant (Fm) via a ii-V (Gm7 - C7), shifting the tonal center briefly to the key of IV.
  • Utilizes the bVI7 (Ab7) as a chromatic passing chord or neighbor tone to the IVm (Fm7), providing a dark, bluesy character.
  • Features a Picardy third resolution at the final cadence, transitioning the C minor tonality to a bright Cmaj7 ending.
  1. Improvisation Focus C Melodic Minor, specifically focusing on the raised 6th and 7th to navigate the tonic minor and its dominant substitutions effectively.

  2. Difficulty Rating 3/5: Navigating the shift to the subdominant bridge and the secondary dominants requires a solid grasp of altered minor harmony beyond basic blues scales.
