- Chromatic descending turnaround ($D7 - Db7 - G7$) utilizing $Db7$ as a tritone substitute for $G7$ or a dominant neighbor chord to create linear bass movement.
- Use of the $bVI7$ chord ($Ab7$) functioning as a tritone substitute for the $V/V$ ($D7$), adding a dark, bluesy tension characteristic of the “film noir” aesthetic.
- Repeated minor ii-V-i cells ($Dm7b5 - G7b9 - Cm$) that anchor the piece in C minor while demanding mastery of altered dominant tensions.
- Bridge modulations that pivot toward the subdominant ($Fm$) and relative major ($Eb$), requiring fluid navigation between parallel and relative harmonic environments.
Improvisation Focus C Melodic Minor, specifically applying the Altered Scale over dominant substitutions to emphasize the chromatic guide-tone voice leading.
Difficulty Rating 3/5; while the slow ballad tempo offers time for thought, the frequent chromatic substitutions and minor-key functional shifts require sophisticated harmonic awareness.
