Harmonic Analysis

This progression moves through F♯dim (Subtonic) → G (Tonic).

The vii°–I progression features the diminished triad built on the leading tone resolving directly to the tonic. The diminished chord's inherent instability — caused by its tritone between root and flat fifth — creates powerful tension that demands resolution. It functions similarly to V–I but with even more urgency, and is a staple of classical part-writing and jazz voice leading.
