Harmonic Highlights
- Employs a modal i-v (Abm7 to Ebm7) foundation, establishing a dark, rhythmic minor atmosphere characteristic of Petrucciani’s Brazilian fusion style.
- Features a sophisticated chromatic descending turnaround (D7b5 - Db7 - Cmaj7#5 - B7 - Bb7b9) utilizing tritone substitutions and constant structures to delay resolution to the dominant.
- Utilizes the bVI chord (Emaj7#11) as a Lydian pivot, creating a bright harmonic lift against the predominant G# minor tonality.
Improvisation Focus Ab Melodic Minor (G# Melodic Minor) to navigate the altered dominant functions and provide the necessary color for the #5 and #11 extensions.
Difficulty Rating 4 (Advanced): The complex chromatic bridge and rapid dominant substitutions demand precise linear navigation and a deep understanding of non-diatonic voice leading.
