Harmonic Analysis

This progression moves through C♯m6 (Tonic) → F♯m (Subdominant).

The i6–iv progression moves from the minor sixth chord on the tonic to the subdominant minor. The added major sixth gives the tonic a ♭ittersweet brightness before settling into the darker subdominant, creating a wistful harmonic color. This motion is characteristic of jazz ballads and film noir scores where emotional ambiguity is desired.
