Harmonic Highlights

  • Employs chromatic tritone substitutions, specifically using A7 as a subV/I to resolve to the Abmaj7 tonic.
  • Features a bridge driven by sequential II-V-I progressions that modulate to the IV (Db major) before cycling back via Dbm7 and Gb7.
  • Utilizes secondary dominants like Bb7 (V/V) and F7 (V/ii) to create strong directional motion toward the standard ii-V-I cadences.

Improvisation Focus Mastery of bebop scales and chord-tone targeting over rapid, modulating II-V sequences.

Difficulty Rating 4/5. High-speed harmonic changes and shifting key centers in the bridge require advanced navigational skills and fluency in the bebop idiom.
