- The iconic “line cliché” features a descending chromatic inner voice (C–B–Bb–A) over a static C minor root, creating evolving harmonic tension through the maj7, m7, and m6 extensions.
- Frequent minor ii-V-i sequences (Dm7b5–G7b9–Cm) reinforce the dark, melancholic C minor tonality and demand mastery of altered dominant resolutions.
- The progression incorporates a Dorian-flavored IV7 (F7) or ii-V leading to the relative major (Eb major), providing essential contrast to the tonic minor sections.
Improvisation Focus C Melodic Minor to navigate the shifting natural 7th and natural 6th intervals within the opening minor sequence.
Difficulty Rating 3/5: The slow tempo provides space for expression, but the chromatic inner-voice movement and minor-key functional harmony require precise guide-tone navigation.
