Harmonic Highlights:
- Initial sections heavily utilize diatonic I-vi-ii-V progressions, firmly establishing C major tonality through functional harmony.
- Features a minor ii-V of D (
Em7b5, A7b9) followed by a iiø-V7 (Dm7b5, G7) resolving to the major tonic Cmaj7, adding a melancholic harmonic color. - A prominent tertiary modulation to E major occurs via a iiø-V7 (
F#m7b5, B7b9) in the new key, providing significant harmonic contrast.
Improvisation Focus: Navigating ii-V-I progressions across shifting key centers.
Difficulty Rating: 3/5 - The common diatonic sections are accessible, but the distinct tertiary modulation to E major requires confident key center shifts.
