Harmonic Highlights:
- Prominent use of Emaj7#11 and Gbmaj7#11 introduces non-diatonic Lydian qualities and chromatic half-step movements within the F minor key center.
- Frequent Db7#11 chords function as tritone substitutes for G7, creating strong secondary dominant resolutions to Cm7 (v).
- The Abmaj7#5 adds a distinctive, bright color over the bIII function, extending its harmonic tension beyond a simple major seventh.
- Inclusion of the unique Dbmb6 (Db minor triad with an added A natural) creates a highly dissonant, complex minor-major-like quality.
Improvisation Focus: Vertical improvisation emphasizing Lydian and altered dominant scales specific to each chord.
Difficulty Rating: 5 (Advanced). Its dense chromaticism, non-functional harmony, and frequent use of complex voicings demand a sophisticated understanding of jazz theory and advanced melodic navigation.
