Harmonic Highlights

  • Employs a chromatic walking bass line that incorporates all twelve tones within the initial A section.
  • Features rapid modulations through distant key centers (C major to Eb major to Ab major) using concise ii-V-I sequences.
  • Utilizes constant structure harmony and deceptive resolutions, such as the D7 to Db7 to Cmaj7 movement, to create fluid tonal shifts.

Improvisation Focus Guide-tone navigation to connect the rapidly shifting transient key centers.

Difficulty Rating 4/5 โ€” The frequent, non-diatonic modulations and the lack of a stable home key require advanced harmonic visualization and quick mental transposition.
