- The progression employs sequential descending ii-V-I patterns, modulating from G major down to F major and then to Eb major, creating a characteristic “drifting” tonal effect.
- Extensive use of b9 and b13 extensions on dominant chords provides a lush, cinematic tension typical of 1940s film noir harmonies.
- A chromatic pivot occurs via the Cm7 to Am7b5 transition, functioning as a sophisticated bridge to return the harmony from Eb major back to the primary G major tonic.
Improvisation Focus Navigating rapid tonal center shifts by targeting 3rds and 7ths within descending ii-V sequences.
Difficulty Rating 4/5: The constant modulation through keys related by minor and major thirds requires advanced harmonic navigation and quick mental transposition.
