Harmonic Highlights

  • Minor ii-V-i progressions (Dm7b5 - G7b9 - Cm) establish the primary melancholic tonality and tension.
  • Dramatic modulation to the parallel major (Cmaj7) provides a brief, bright contrast to the minor sections.
  • Secondary ii-V motion (Gm7 - C7 to Fmaj7) followed by a backdoor bVII7 (Bb7) creates sophisticated voice leading back to the tonic.

Improvisation Focus C Melodic Minor, utilizing the major 6th (A) and major 7th (B) to navigate the tonic minor and its associated line clichés.

Difficulty Rating 3/5: Navigating the rapid shifts between the brooding C minor foundation and the bright parallel major bridge requires precise scalar awareness.
