Harmonic Highlights
- The piece opens with a prolonged B7#11, immediately establishing a Lydian Dominant quality rather than a simple B major tonic.
- Features a sophisticated descending V7 cycle (Bb7b13-Eb7-Ab7b13-Db7), showcasing intricate dominant alterations.
- Frequent chromatic shifts and strong ii-V-I cadences in keys like Db major and D major demonstrate fluid, non-diatonic modulation.
- The consistent use of altered extensions (#11, b13, #5, b9) on dominant chords creates a rich, modern harmonic palette.
Improvisation Focus Navigating altered dominant scales (e.g., Lydian Dominant, Altered Scale) is paramount.
Difficulty Rating 5 (Advanced). The rapid, non-diatonic modulations and prevalent use of complex altered dominants require sophisticated harmonic insight.
