Harmonic Highlights:
- Features abrupt and frequent modulations, notably the sudden shift to a ii-V-I in B major (C#m7-F#7-Bmaj7) from an implied C minor/major context.
- Employs a series of ii-V-I progressions to tonicize diverse key centers, including C minor/major, B major, and Ab major, creating a harmonically rich and unpredictable journey.
- The juxtaposition of Ab major (the subdominant of the home key Eb) with the distantly related B major highlights a dynamic interplay between familiar and remote tonal areas.
Improvisation Focus: Focus on accurately outlining each ii-V-I progression using appropriate chord-scales to navigate rapid and distant key changes.
Difficulty Rating: 5 (Advanced) due to the demanding modulations to distantly related keys and the intricate harmonic rhythm.
