Harmonic Highlights:
- Features an array of sequential ii-V-I progressions that swiftly modulate to new key centers (e.g., D, Eb, Db, C, Ab major).
- Exhibits frequent half-step and whole-step root movements between target I chords of consecutive ii-V-Is (e.g., D to Eb, Db to C).
- Characterized by a dense harmonic rhythm, with chord changes occurring every one or two beats, demanding constant harmonic recalibration.
- Includes unexpected alterations and substitutions, like the B7 following Cm7, hinting at complex harmonic movements beyond simple diatonicism.
Improvisation Focus: Superimposing arpeggios and modes aligned with each chord’s quality and function.
Difficulty Rating: 5 (Advanced) - Its relentless harmonic rhythm and rapid, often unexpected modulations demand sophisticated knowledge of harmony and exceptional technical fluidity.
