Harmonic Highlights
- Features extensive use of secondary dominant cycles and ii-V-I progressions, notably Em7b5-A7b9 targeting D minor.
- Includes a clear tonicization of the subdominant with a Cm7-F7-Bbmaj7 ii-V-I, adding harmonic color.

Improvisation Focus Navigating dominant alterations and substitutions is crucial.
Difficulty Rating 4 (Advanced Intermediate) - Requires proficiency in navigating frequent modulations, secondary dominants, and a back-door ii-V progression.
