Harmonic Highlights:
- Juxtaposes strong diatonic II-V-I progressions in D major with unexpected chromatic mediant shifts (e.g., Cmaj to Dmaj, Bmaj to Cmaj).
- Utilizes tritone substitutions (e.g., Ab-Db implying G7-C/F) and secondary dominants (F#-B) to navigate through rapid, non-diatonic tonal areas.
- Incorporates ‘sus’ chords (Csus) for open, modal sounds, creating tension and leading to surprising resolutions or harmonic departures.
Improvisation Focus: Harmonic adaptability across rapidly shifting tonal centers.
Difficulty Rating: 5 (Advanced). The rapid, non-diatonic chord changes and frequent modulations require sophisticated harmonic understanding and strong ear training.
