Harmonic Highlights:

  • Features a recurrent ii-V-I progression to the bVI (Bbm7-Eb7-Abmaj7) within the C minor framework, creating a strong subdominant pull.
  • Employs the classic minor iiø-V-i progression (Dm7b5-G7#5-Cm7), with the G7#5 indicating an altered dominant sound.
  • Includes a brief, unexpected tonicization of C major (Cmaj7-G7) before resolving back to the C minor tonality.

Improvisation Focus: Navigating altered dominant scales (e.g., G7#5) and smoothly transitioning between C minor and Ab major harmonies.

Difficulty Rating: 4 (Advanced) - It demands proficiency in navigating complex harmonic substitutions and altered dominant sonorities within a minor key context.
