Harmonic Highlights:

  • Prominent use of a passing diminished chord (C#0) functioning as vii°7/ii, leading effectively to Dm7.
  • Extended tonic embellishment in C major using C6 and Cmaj7 chords before moving away from the tonic.
  • A temporary modulation to Bb major is established through a ii-V-I progression (Cm7-F7-Bb6), creating a distinct shift to the bVII key.

Improvisation Focus: Navigating major scales and arpeggios over varying ii-V-I progressions and key modulations.

Difficulty Rating: 4 (Advanced Intermediate). The frequent modulations to distant keys and the use of passing diminished chords require a solid grasp of functional harmony and multiple key centers.
