Harmonic Highlights
- Prominent use of Ab7#11 (I7#11) as the tonic sonority, establishing a distinctive Lydian Dominant character over the root.
- Sudden, distant modulations are evident with the Bm7-E7 progression, suggesting a temporary tonicization of A major, far from Ab.
- Unconventional dominant resolutions appear, such as D7b5 moving to Ebmaj7, defying typical functional V-I expectations.
- Chromaticism is high, notably with the F7#9 and A9 chords, creating significant harmonic tension and ambiguity.
Improvisation Focus The Lydian Dominant scale is paramount for the I7#11, complemented by various altered scales for the numerous dominant chords.
Difficulty Rating 5 (Advanced) โ Complex modulations, pervasive altered dominant voicings, and non-diatonic resolutions demand a sophisticated harmonic understanding and agile execution.
