Harmonic Highlights:
- Extensive use of tritone relationships, notably an initial
Emaj7and 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.
