Harmonic Highlights:
The tune extensively utilizes ii-V-I progressions, rapidly tonicizing multiple major keys, including Eb, C, and Bb, deviating significantly from the initial C minor.
A notable modulation occurs from an implied C minor through its relative major (Eb) before unexpectedly tonicizing C major (parallel major).
The Dm7-G7-Cmaj7 progression provides a sudden, bright shift to the parallel major, creating strong harmonic contrast.
Subsequent ii-V-I progressions like Cm7-F7-Bbmaj7 further demonstrate a sophisticated and highly migratory harmonic structure.
Improvisation Focus: Navigating rapid chord-scale changes and precise arpeggio outlining for each transient tonic.
Difficulty Rating: 4 (Advanced Intermediate) โ Requires strong command of multiple key centers and quick harmonic anticipation due to frequent modulations and non-diatonic ii-V-I movements.
