Harmonic Highlights:
- The Eb7#11 (bVII7#11) introduces a distinctive altered dominant sound, creating harmonic richness and unexpected tension within dominant progressions.
- Chromatic dominant successions like F7-Gb7-G7 build tension and propel the harmony through secondary dominant cycles.
- Blues-infused chromatic alterations such as D7-Eb7-D7 add expressive depth while momentarily shifting tonal color around secondary dominants.
- The Ab7 (bVII7) provides a classic backdoor dominant resolution to the tonic, imbued with a soulful Ellingtonian character.
Improvisation Focus: Navigating altered dominant scales and chromatic voice leading over unexpected chord changes.
Difficulty Rating: 4 (Advanced Intermediate) – The frequent use of non-diatonic chords, chromatic passing dominants, and altered tensions requires a sophisticated harmonic understanding.
