Harmonic Highlights:
- Frequent, often rapid, modulation to closely related keys’ relative majors (e.g., ii-V-I to Ebmaj7 (bVI) and Abmaj7 (bIII)).
- Prominent descending chromatic minor 7th chord sequences (e.g., Cm7-Bm7-Bbm7), creating tension and smooth voice leading.
- Strategic use of tritone substitutions (e.g., Db7 replacing G7) and altered dominant chords to propel chromatic harmonic motion.
- Exploration of parallel major/minor and chromatic mediant relationships (e.g., Dbmaj7 after Ebmaj7) enriching the harmonic texture.
Improvisation Focus: Navigating temporary tonal centers through precise arpeggio outlining and appropriate modal applications.
Difficulty Rating: 4 (Advanced) - Advanced due to rapid and sometimes non-diatonic modulations requiring strong harmonic anticipation and detailed chord-scale knowledge.
