Harmonic Highlights:
- Characterized by a rapid harmonic rhythm, frequently employing ii-V-I progressions that tonicize temporary key centers like Ab major (bIII) and Db major (bVI).
- Heavy reliance on secondary dominants (e.g., F7 to Bb, Bb7 to Eb) to generate forward motion and introduce new temporary tonics.
- The constant modulation and quick succession of chord changes result in a highly chromatic and harmonically dense framework.
Improvisation Focus: Precise outlining of rapidly changing harmonies using appropriate arpeggios and scales.
Difficulty Rating: 5 (Advanced) Its rapid harmonic rhythm, frequent modulations, and complex chord changes demand advanced technical and harmonic proficiency.
