- Employs “side-slipping” by oscillating between Fmaj7 and Gbmaj7, replacing the traditional I-VI-ii-V with a chromatic Neapolitan relationship.
- Utilizes heavy tritone substitutions (Db7 for G7) and dominant chains (B7-A7-D7-G7) that prioritize chromatic voice leading over functional diatonicism.
- Features advanced upper-structure tensions, such as Gbmaj7#11 and Db7#5, to emphasize Lydian and Whole-Tone sonorities within a fast-moving harmonic rhythm.
Improvisation Focus Chromaticism and Chord Tone Targeting—specifically navigating the half-step shifts between F major and Gb major tonalities while maintaining linear logic.
Difficulty Rating 4 (Advanced) The rapid harmonic rhythm and constant non-functional chromatic shifts require advanced ears and the ability to connect disparate tonalities at high tempos.
