No obvious ii-V patterns detected.


  • The segment is characterized by a pervasive C pedal point, creating a static bass foundation while enabling dense and complex upper structure harmony.
  • Frequent use of altered dominant chords (Caug, F#aug/C implying G7#5b9) and chromatic alterations over the C pedal creates tension and leads to varied sonorities.
  • Modal interchange is prominent with Fm7/C and Fm/maj7/C, borrowing minor harmony against the F major key center, adding a contemplative color.
  • The shifting upper structures like Bbmaj7/C, Cm9, Cm11, and Bbmaj7#5/C provide a rich harmonic palette that constantly evolves over the steady C pedal.

Improvisation Focus: Navigating and outlining the specific upper structure voicings over the C pedal point.

Difficulty Rating: 5 (Advanced). The constant C pedal demands precise melodic contouring and harmonic superimposition to articulate the rapidly changing and complex upper structures.
