Harmonic Highlights:
- Non-functional major 7th chords (e.g., Abmaj7, Dbmaj7) introduce early modal ambiguity and color beyond diatonic expectations in G# minor.
- Frequent ii-V progressions to distantly related minor keys (e.g., Gm7b5-C7b9 to F minor, Bbm7b5-Eb7b9#11 to Ab minor) create continuous, shifting tonicizations.
- Prominent use of modal interchange major 7ths (e.g., Bmaj7, Emaj7 derived from G# natural minor) adds harmonic richness and characteristic Shorter voicing.
- Suspended dominants (e.g., Db7sus, A9sus, Gb9sus) contribute to harmonic tension, often leading to ambiguous resolutions or further chromatic shifts.
Improvisation Focus: Melodic minor modes to navigate the shifting dominant and minor qualities.
Difficulty Rating: 5 (Advanced) – The frequent, often non-functional modulations and altered dominant voicings require sophisticated harmonic understanding and a highly adaptive improvisational approach.
