Harmonic Highlights:
- The opening bVIImaj7 - bVIIm/maj7 - Imaj7 progression (Dbmaj7 - Dbm/maj7 - Abmaj7) is a signature Tristano harmonic device, often termed a “backdoor” ii-V.
- Extensive use of altered dominant chords like F7#11 (V7 of Bbm7) introduces Lydian Dominant tension and color.
- A prolonged cycle-of-fifths dominant progression (C7, F7, Bb7, Eb7) creates extended harmonic motion and reharmonization opportunities.
Improvisation Focus: Precise navigation of altered dominant scales and arpeggios.
Difficulty Rating: 5 (Advanced). The rapid harmonic rhythm, frequent altered dominants, and extended cycles demand sophisticated theoretical understanding and technical precision.
