Harmonic Highlights:
- Prominent use of a descending chromatic dominant movement (
F7toE7#9), indicating advanced reharmonization and voice leading. - Non-functional dominant resolutions, such as
E7#9toDb, showcasing Herbie Hancock’s characteristic chromaticism and harmonic ambiguity. - Extended modal vamping, particularly the prolonged
Dm(iii chord) withBb7(I7), creating a departure from strict functional harmony. - Incorporation of non-diatonic chords like
DbandEb7as pivot points, enriching the harmonic landscape and challenging traditional expectations.
Improvisation Focus: Altered Scale application over the chromatic dominant chords.
Difficulty Rating: 4 (Advanced Intermediate). The complex chromatic dominant movements and non-functional progressions demand a sophisticated harmonic understanding.
