Harmonic Highlights

  • Pedal Point Tension: The composition utilizes a prolonged B pedal, creating a suspended modal atmosphere through B7sus.
  • Slash Chord Parallelism: The movement from Db7/B to Cmaj7/B introduces polychordal tension, shifting harmonic color from Lydian Dominant to a dark Phrygian resolution over the tonic.
  • Chromatic Dominant Planning: The descent through B7, Bb7, and A7 functions as a non-functional bridge, leading into a hard-bop turnaround.
  • Modal-Tonal Hybrid: The structure oscillates between static modal zones and functional minor-key turnarounds (F#7#9 to Bm).

Improvisation Focus B Mixolydian and B Phrygian Dominant scales, emphasizing upper-structure extensions over the B pedal.

Difficulty Rating 4/5: Navigating the transition from static modal sections to rapid, unconventional chromatic shifts requires advanced harmonic awareness and melodic flexibility.
