Harmonic Highlights:

  • Striking chromatic shifts between Bbmaj7 and Bmaj7/Bb create a “sidestepping” effect, where the root moves chromatically while the bass may remain stable.
  • Extensive use of a Bb pedal point under diverse upper structures like Ebmaj7, F, Bmaj7, and C triads, generating tension and a floating harmonic texture.
  • Integration of non-diatonic elements such as Bb07 and C/B indicates advanced modal interchange and coloristic harmony, adding complexity beyond standard functional progressions.

Improvisation Focus: Chromatic superimposition.

Difficulty Rating: 5 (Advanced). Requires sophisticated harmonic understanding to navigate frequent non-diatonic chord movements and chromatic pedal points, demanding a high level of aural and theoretical skill.
