Harmonic Highlights:
- The recurring G7/B functions as a V7/I in C minor, often with chromatic bass movement, strongly re-establishing tonic.
- The striking Bbm6 to F/A progression introduces unexpected major tonality and a brief modal shift, creating harmonic interest.
- Frequent ii-V-I cycles in the relative major (Fm7-Bb7-Ebmaj7) and dominant minor (Am7b5-D7b9-Gm7) create clear, yet shifting, temporary tonal centers.
- The use of Abm6 adds a distinct modal color, often functioning as a chromatic embellishment or an implied dominant preparation.
Improvisation Focus: Navigating altered dominant scales (e.g., Half-Whole Diminished, Altered Scale) over the various V7b9 and D7 chords.
Difficulty Rating: 4 (Advanced). The tune requires proficiency in rapidly navigating modulations, non-diatonic chords, and complex dominant resolutions.
