Harmonic Highlights
- Employs a relentless chain of dominant 7th chords, utilizing both cycle-of-fourths movement (D7-G7-C7) and rapid chromatic parallelisms.
- Transforms the “Tea for Two” blueprint into a high-speed exercise in tritone substitutions and unresolved dominant tensions.
- Features a symmetrical harmonic approach where dominant structures are shifted linearly, bypassing traditional functional cadences in favor of “side-slipping.”
Improvisation Focus Symmetrical scales (Whole-Tone) and Lydian Dominant flexibility.
Difficulty Rating 5/5. The combination of high-speed harmonic turnover and the demand for precise alterations over non-functional dominants creates an extreme challenge for any improviser.
