Harmonic Highlights
- The composition opens with eight measures of static F13, establishing a modal, unmoving harmonic landscape before introducing dynamic movement.
- Features frequent, non-diatonic altered dominant chords (E7#9, B7#5#9, C7#9, C7alt) leading to unexpected resolutions or temporary tonal centers.
- Showcases distinct modulations through ii-V-I progressions, notably an excursion to F minor (Gm7-C7#9-Fm7) and a significant shift to Db major (Ebm7-Ab13-Dbmaj9).
Improvisation Focus The Altered scale (Super Locrian) over the numerous altered dominant chords.
Difficulty Rating 5 (Advanced). Navigating the rapid, non-functional modulations and pervasive altered harmony requires highly developed harmonic perception and quick adaptation.
