Harmonic Highlights
- Opens with a rapid sequence of ii-V-I cycles modulating through major-third related key centers (F, Ab, B), akin to “Giant Steps” changes.
- Employs extended ii-V-I progressions, often incorporating secondary dominants like G7b13 (V/ii) leading to Cm7-F7-Bbmaj7.
- Features chromaticism, including sudden shifts and descending minor 7th chord planing (Cm7, C#m7, Bm7) for constant motion.
Improvisation Focus Accurately outlining complex, rapidly changing chord tones.
Difficulty Rating 5 (Advanced) – The extremely rapid harmonic rhythm and constant, distant modulations demand exceptional harmonic fluency.
