Harmonic Highlights

  • Employs standard ii-V-I cadences in Eb major that pivot via a minor ii-V-i (Dm7b5-G7-Cm7) to reach the relative minor.
  • Utilizes secondary dominants (F7) to create tension and drive the harmony back toward the secondary ii-V (Fm7-Bb7) sequence.
  • Features a signature Tyner chromatic shift, moving from the Ab7 dominant area into a distant ii-V in E major (F#m7-B7) through side-slipping.

Improvisation Focus Pentatonic shifting (specifically Eb and E major pentatonics) to navigate the abrupt non-diatonic modulations.

Difficulty Rating 3/5: The progression combines predictable diatonic sequences with sudden shifts to remote keys, requiring quick mental transposition.
