Harmonic Highlights:
- A direct chromatic shift from Bm9 to Bbmaj7#11 establishes an immediate non-diatonic harmonic language.
- The progression then employs a series of whole-step descents (Bbmaj7#11 -> A13sus -> G69), creating a floating, non-functional movement.
- G69 functions as a colorful bVI chord in relation to the B minor key center, leading back to the tonic Bm9 in an extended loop.
Improvisation Focus: The chord-scale approach, precisely outlining each distinct harmony.
Difficulty Rating: 4 (Advanced). The rapid non-diatonic shifts and implied modal changes require agile harmonic navigation and a strong understanding of complex chord-scale relationships.
