Harmonic Highlights:
- Frequent half-step chromatic shifts, notably
Bbm7toBm7andF#m7toGm7, creating immediate tonal displacement. - Descending chromatic sequence of major and dominant 7th chords (
Amaj7, Ab7, Gmaj7, Gb7) for smooth voice leading and temporary modulation. - Rapid juxtaposition of
ii-Vprogressions that temporarily pivot to new tonal centers, challenging diatonic expectations.
- Frequent half-step chromatic shifts, notably
Improvisation Focus: Arpeggio navigation with chromatic approach notes to connect rapidly shifting chord tones.
Difficulty Rating: 4 (Advanced Intermediate) because of the numerous non-diatonic chords, rapid modulations, and intricate voice leading demanding high harmonic awareness.
