Harmonic Highlights:
- The interplay of bVIImaj7 (Bbmaj7) and ii-V-i (Dm7-G7-Cm7) establishes a distinct C minor modal sound.
- A rapid descending cycle of ii-V changes (
Fm7-Bb7-Eb7-Ab7) creates intense harmonic drive, characteristic of the bridge section. - Prominent dominant chains like
D7-G7-C7-F7establish a strong, forward-moving harmonic rhythm, common in Rhythm Changes A sections.
Improvisation Focus: Navigating chord tones and specific chord-scales for each rapid harmonic change.
Difficulty Rating: 5 (Advanced). The rapid tempo, dense harmonic rhythm, and frequent modulations demand exceptional technical proficiency and harmonic understanding.
