Harmonic Highlights:

  • Features frequent ii-V-i progressions in C minor (Dm7-G7-Cm7) and dominant preparations like D7 (V/V).
  • Incorporates a bVIImaj7 (Bbmaj7) often preceding the tonic minor, hinting at Dorian or modal interchange.
  • Employs extended cycle of 5ths movement with dominant 7ths (Fm7-Bb7-Eb7-Ab7), driving rapid harmonic changes and implied modulations.
  • Utilizes V7/IV (C7) leading to F7, suggesting temporary tonicization of F or a blues-inflected progression.

Improvisation Focus: Mastering chord tones, extensions, and bebop scales over rapid ii-V-I and cycle-of-fifths progressions.

Difficulty Rating: 5 (Advanced). Requires exceptional facility with fast harmonic rhythm, complex chord changes, and navigating multiple temporary key centers.
