- The progression opens with a IVmaj7 to IVm(maj7) movement (Dbmaj7 to Dbm/maj7), utilizing the melodic minor on the minor-subdominant for a sophisticated “cool jazz” tension.
- It modifies “Rhythm Changes” by extending the bridge’s secondary dominant cycle (C7-F7-Bb7-Eb7) across two measures per chord, requiring sustained harmonic development.
- The F7#11 chord functions as a secondary dominant (V/ii) with a Lydian Dominant color, creating a sharp chromatic leading tone toward Bbm7.
Improvisation Focus Linear chromaticism and rhythmic displacement over the Ab major/Db melodic minor relationship.
Difficulty Rating 4/5: The piece demands high-speed technical precision and the ability to navigate extended dominant cycles within Tristano’s characteristically dense contrafact structure.
