Harmonic Highlights
- Features extensive direct modulations, notably establishing a Bb major tonicization (Bb6, Gm7, Cm7, F7#9) distant from the stated D major key center.
- Utilizes clear ii-V-I progressions for temporary tonicizations, demonstrated by Cm7-F7#9 to Bb and Ab7 to Dbmaj7.
- Incorporates tritone substitutions (e.g., Ab7) and altered dominant voicings (F7#9) for rich chromaticism and tension.
Improvisation Focus Navigating rapid and distant modulations with precise chord-scale application.
Difficulty Rating 5 (Advanced) – Its frequent, distant modulations and sophisticated use of altered dominants demand high-level harmonic comprehension.
