Harmonic Highlights
- Uses chromatic dominant chains (E7#11 to Eb7) that utilize tritone substitution logic to create tension and downward melodic motion.
- The Gb/C functions as a C7alt chord (bII of the V), serving as a sophisticated chromatic turnaround leading to the F7#5.
- The composition reinterprets the minor blues framework by alternating between static Bbm7 plateaus and dense, non-functional dominant movements.
Improvisation Focus Bb Dorian and Minor Pentatonic for stability, transitioning to Lydian Dominant scales to navigate the #11 extensions.
Difficulty Rating 4/5: The rapid non-functional dominant shifts and unconventional slash chords require precise modal navigation and advanced harmonic vocabulary.
