Harmonic Highlights:

  • Extensive use of tritone relationships, notably an initial Emaj7 and a full ii-V-I in E major (F#m7-B7-Emaj7), a tritone away from Ab.
  • Frequent, abrupt modulations via ii-V-I progressions (e.g., Ebm7-Ab7-Dbmaj7), establishing multiple temporary tonal centers.
  • Chromatic dominant 7th chord movement (e.g., Ab7-G7-Cmaj7), creating unexpected harmonic shifts and deceptive resolutions.

Improvisation Focus: Chord-Scale Navigation.

Difficulty Rating: 5 (Advanced) - The rapid, non-diatonic modulations and complex harmonic rhythm demand sophisticated chord-scale knowledge and agile execution.
