Harmonic Highlights:
- The G7-Cm7 progression serves as a foundational V-i resolution, frequently re-establishing C minor as a recurring tonal center.
- The Bbmaj7 (bVIImaj7) chord offers a modal color or temporary tonic, preceding the drive towards C minor.
- Rapid modulation through ii-V-I progressions (e.g., Fm7-Bb7-Eb7) and dominant cycles (D7-G7-C7-F7) defines the form’s dynamic harmonic landscape.
- Constant harmonic motion, particularly in the bridge, demands agile navigation across multiple, often briefly established, tonal centers.
Improvisation Focus: Arpeggios and chord tones, emphasizing smooth voice leading through ii-V-I progressions.
Difficulty Rating: 5 (Advanced). The fast harmonic rhythm and constant modulations through various temporary key centers demand advanced harmonic and improvisational agility.
