Harmonic Highlights
- The recurring
Dbmaj7 - Ebm7b5/Dbsequence creates a static, ambiguous sound, featuring tension with b3 and b5 intervals against the Db pedal. - Frequent use of highly altered dominant chords, such as
G7b5b9andC7#9, introduces significant chromaticism and temporary tonicizations outside of Ab major. - The
Abm7/Dbchord functions as aDb7(#11, 13)(Db Lydian Dominant), providing a rich, altered dominant color. - The
Fm7 - Bbm7 - Ebm7progression establishes a clear ii-V-I movement to Eb (or vi-ii-v in Ab), momentarily grounding the harmony within functional cycles.
Improvisation Focus Altered dominant scales (Lydian Dominant, Altered) and the ability to navigate complex tensions over pedal point harmonies.
Difficulty Rating 5 (Advanced) - The intricate non-diatonic voicings, rapid altered dominant resolutions, and ambiguous pedal point harmonies require sophisticated harmonic understanding.
