Harmonic Highlights:
- The piece frequently tonicizes distant keys (e.g., F major, Bb major, A major, Db major) via standard ii-V or iiø7-V7 progressions.
- Prominent use of non-diatonic major seven chords (Bmaj7, Amaj7, Dbmaj7) that serve as temporary tonal centers, creating unexpected harmonic shifts.
- Incorporates chromatic dominant movement, such as C7alt descending to B7#11, suggesting advanced voice leading and tritone substitution techniques.
Improvisation Focus: Navigating arpeggios and chord-scales precisely over rapidly shifting temporary tonics.
Difficulty Rating: 4 (Advanced Intermediate) - The rapid and distant modulations require a strong grasp of chord-scale theory and harmonic anticipation.
