Harmonic Highlights
- Frequent use of ii-V-I progressions, notably Bbm7-Eb7-Abmaj7 (a ii-V-I in the subdominant key).
- Employs passing diminished chords like Gb07 and A07, adding chromatic color and tension between diatonic chords.
- Features a striking modulation to remote keys via descending ii-V sequences (Ebm7-Ab7 to Db, Dbm7-Gb7 to B), showcasing advanced harmonic movement.
- The Bmaj7-E7#11 movement provides a significant chromatic shift and dominant function leading into the modulating section.
Improvisation Focus Accurately outlining chord tones and applying appropriate dominant scales across frequent, often remote, modulations.
Difficulty Rating 4 - The extensive use of non-diatonic chords and rapid modulations to distant keys demands a high level of harmonic awareness.
