Harmonic Highlights:
- The piece quickly establishes F minor (Cm7 as iv), then embarks on a non-functional sequence of ascending and descending major 7#11 chords (Dbmaj7#11, Ebmaj7#11, Emaj7#11, Dmaj7#11), creating sophisticated chromatic color.
- Extensive deployment of major 7#11 chords suggests a consistent Lydian quality across various tonal centers, moving away from conventional functional harmony.
- The F13b9 functions as a V/Bbm, leading to a poignant Bbm/maj7 (iv in F minor with a unique tonic quality), subsequently followed by a Gm7b5 initiating a ii-V movement.
Improvisation Focus: Navigating the sequential chromatic major 7#11 chord changes using Lydian modes.
Difficulty Rating: 5 (Advanced) - The pervasive non-functional chromaticism and advanced chord voicings require a high level of harmonic sophistication and improvisational technique.
