Harmonic Analysis

This progression moves through Fm (Tonic) → FmMaj7 (Tonic) → Fm7 (Tonic) → Bbm (Subdominant).

The i–imaj7–i7–iv progression is the classic chromatic line cliché in minor keys. A single voice descends chromatically from the octave through the major seventh and minor seventh while the rest of the chord remains static, creating a hypnotic, cinematic effect. This descending bass line or inner-voice motion is one of the most recognizable sounds in film music and jazz ballads.
