Harmonic Highlights
- Features descending dominant 7th chains (e.g., G7-C7-F7-Bb7) driving forward harmonic motion.
- Employs intricate minor ii-V-i progressions (e.g., Gm7b5-C7b9-Fm7, Am7b5-D7b9-Gm7) creating rich tension and resolution.
- Utilizes tritone substitutions (e.g., B7#9 resolving to Bbmaj7) and secondary dominants for chromatic interest and unexpected turns.
Improvisation Focus Targeting chord tones and extensions across diverse ii-V-I and dominant cycles.
Difficulty Rating 5 (Advanced). Its rapid harmonic rhythm, frequent modulations, and complex ii-V-I progressions demand sophisticated improvisational skills.
