- Harmonic Highlights:
- Utilizes repeating V7/V to V7 cycles (Bb7 to Eb7) that shift chromatically (to B7 to E7), creating a “side-slipping” effect that delays resolution to the G# minor tonic.
- Employs constant structure dominant chords with specific #5 and #9 extensions, demanding precise vertical alignment rather than traditional functional voice leading.
- Features a sophisticated bIImaj7 to bV7 (Amaj7 to D7#11) transition, utilizing Lydian and Lydian Dominant colors to bridge disparate tonal centers.
Improvisation Focus: The Altered Dominant scale (Super Locrian) is the primary tool for navigating the specific #5 and #9 tensions within the shifting dominant vamps.
Difficulty Rating: 4/5. The non-standard form and relentless chromatic transposition of altered dominant chords require advanced modal fluency and high-level harmonic navigation.
