Harmonic Highlights:
- Extensive use of secondary dominants (e.g., G7 as V/ii, Bb7 as V/IV) to propel the harmony and create brief tonicizations.
- Frequent ii-V-I progressions, appearing both diatonic (Cm7-F7-Bbmaj7) and temporarily tonicizing the subdominant (Fm7-Bb7-Ebmaj7).
- Features a characteristic bebop descending dominant chain (D7-G7-C7-F7) creating strong harmonic tension leading to the tonic’s dominant.
Improvisation Focus: Bebop scales and advanced arpeggio outlining for rapid chord changes.
Difficulty Rating: 5 (Advanced) - Demands proficient command of altered scales, chromaticism, and rapid harmonic navigation across multiple, fleeting key centers.
