- The opening features an extended, rapid chromatic oscillation between dominant 13th chords (Bb13 - B13), generating intense tension and harmonic ambiguity around the dominant of Eb minor.
- Non-diatonic ii-V-I progressions, such as Cm7-F7#5-Bbmaj7, temporarily shift the tonal center away from Eb minor, creating a sense of tonal flux.
- Shorter employs chromatic mediant and submediant relationships, evidenced by movements like Abmaj7 to Gbmaj7, further embellished by altered dominant chords (e.g., G7b9).
Improvisation Focus: Chromaticism.
Difficulty Rating: 4 (Advanced). The rapid non-diatonic harmonic shifts, altered dominants, and complex modulations demand precise harmonic navigation.
