  • The opening Bbmaj7 functions as a bVIImaj7, preceding the G7 (V7 of C minor) for an unconventional tonic approach.
  • Rapid key center shifts are evident with the Dm7-G7 (ii-V in C major) followed by a return to Cm7, creating harmonic dynamism.
  • Extended descending dominant movement (e.g., Fm7-Bb7-Eb7-Ab7) showcases complex bebop reharmonization and modulation.
  • Secondary dominants like D7 (V7 of G) and C7 (V7 of F) create chains of tension leading to subsequent dominant chords.
