Harmonic Highlights:
- Frequent, often abrupt, modulations and tonicizations to various keys including Eb major, F major, and C minor.
- Prominent use of non-diatonic major chords (Bbmaj7, Abmaj7) creating chromatic mediant relationships and parallel shifts.
- Extensive application of altered dominant chords (E7b9, A7b13, G7b9) to enhance tension and resolution.
- Recurring minor and major ii-V-I progressions facilitate smooth transitions between temporary tonal centers.
Improvisation Focus: Navigating constant key changes with precise chord-scale application for each new tonal center.
Difficulty Rating: 4 (Advanced Intermediate) - The rapid and often non-diatonic modulations require sophisticated melodic and harmonic understanding to improvise effectively.
