Harmonic Highlights
- The tune extensively features a prolonged C7 (eight bars) as a tonic dominant, deviating from a typical Cmaj7 and establishing a blues-infused or Lydian dominant character.
- Frequent modal interchange is evident with the use of bVImaj7 (Abmaj7) and bVIImaj7 (Bbmaj7), expanding the harmonic palette beyond C major.
- Characteristic Tristano reharmonizations include the non-diatonic Eb7-D7 movement (tritone substitution leading to a secondary dominant) and the complex Cm7-C#07-Bbmaj7 progression.
- A standard iiø7-V7b9-i progression (Bm7b5-E7b9-Am7) provides a clear, albeit temporary, tonicization of the relative minor.
Improvisation Focus Precise chord-scale application to navigate rapid, non-diatonic harmonic shifts.
Difficulty Rating 4 (Advanced) – Requires a sophisticated understanding of modal interchange, altered dominants, and complex voice leading to improvise effectively.
