- Static Bb pedal point creates a drone effect, anchoring shifting upper-structure triads and chromatic neighboring chords.
- Chromatic “side-slipping” between Bbmaj7 and Bmaj7/Bb introduces sharp non-diatonic tension (bII/I) that bypasses traditional functional resolution.
- Modal interchange and Lydian colors are emphasized through C/Bb and Ebmaj7/Bb, providing bright, open-ended harmonic extensions.
- Symmetrical Bb diminished (Bb°7) chords function as neighbor-tone embellishments to the tonic Bbmaj7 rather than as functional leading-tone dominants.
Improvisation Focus The Bb Lydian scale (Bb, C, D, E, F, G, A) to manage the persistent #11 tension and Lydian-major brightness over the pedal.
Difficulty Rating 4 (Advanced) because the lack of standard functional cadences requires the soloist to maintain melodic momentum and structural logic over static, non-functional shifts.
