Harmonic Highlights:

  • The piece opens and frequently returns to Cmaj7, rather than C minor, establishing a bright, albeit non-diatonic, tonic center against the stated key.
  • Multiple sequential ii-V-I progressions are utilized, resolving to various major keys such as Eb, Ab, G, and C, showcasing rapid modulations.
  • A distinctive section features major 7th chords progressing by a major third then perfect fourths (e.g., Cmaj7, Ebmaj7, Abmaj7, Dbmaj7), introducing rich, non-diatonic harmonic shifts.

Improvisation Focus: Navigating chord tones and specific modes for each individual chord.

Difficulty Rating: 4 (Advanced) - The rapid harmonic rhythm, frequent modulations, and non-diatonic major 7th cycles require sophisticated melodic and harmonic understanding.
