Harmonic Highlights:
- Establishes initial C major diatonicism (Cmaj7, Dm7, Em7) before introducing chromatic alterations.
- Employs C#07 as a vii°7/ii, functioning as a secondary diminished chord that resolves to Dm7.
- Features a significant, yet transient, modulation to Eb major (Ebmaj7/Bb) via a ii-V (Dm7b5-G7) implying a parallel minor relationship.
- Includes a clear tonicization of the subdominant (Fmaj7/F6) via its diatonic chords (Gm7, Am7), creating a temporary shift to F major.
Improvisation Focus: Navigating transient modulations and their associated chord-scale relationships.
Difficulty Rating: 4 (Advanced Intermediate) – The substantial chromaticism and key center shifts, particularly the Eb major section, demand careful scale and arpeggio choices beyond simple diatonic playing.
