Pivot chord modulation

Definition

Pivot chord modulation is a technique used in music composition where a chord that is common to both the original key and the new key serves as a bridge between the two. This method creates a smooth transition, allowing composers to shift from one tonal center to another while maintaining coherence in the harmonic progression. It relies on the shared function of the pivot chord in both keys, making it a sophisticated tool in advanced harmony techniques.
