Harmonic Highlights:

  • Utilizes a chromatic “sidestepping” dominant, B9#11, resolving to Cm11, creating a distinctive non-functional half-step approach to the tonic minor.
  • Features an embedded ii-V-i progression in G minor (Am7b5 D7b9 Gm7) followed by a V7/iv (C7), momentarily shifting tonal centers before returning to C minor.
  • Includes a bold modulation to the Neapolitan major (Dbmaj7 via Ebm7 Ab7), showcasing an adventurous expansion of the harmonic landscape.

Improvisation Focus: Skillful application of Altered and Lydian Dominant scales.

Difficulty Rating: 5 (Advanced) - The complex chromaticism, frequent modulations, and non-functional harmony demand sophisticated harmonic understanding and execution.
