Harmonic Highlights
- Frequent iiø7-V7-i progressions establishing temporary minor tonics, as seen with Dm7b5-G7b9-Cm7.
- Rapid sequential modulations through various ii-V-I cycles, exemplified by the C7#9 to Fm7 and the Bb7sus-Ebmaj7 resolution.
- Incorporation of chromatic major chords and altered tonics (Abmaj7, Cmaj7#5, Fmaj7#11) for color and extended harmony.
- Extensive use of altered dominant chords (G7b9, C7#9) and suspended dominants (Bb7sus, G7sus, G13) to create tension and drive.
Improvisation Focus Applying specific chord-scales and arpeggios to navigate rapid, altered modulations across temporary key centers.
Difficulty Rating 5 (Advanced) due to the dense chromaticism, quick harmonic rhythm, and multiple key center shifts.
