Common chord modulation

Definition

Common chord modulation is a technique used to shift from one key to another by utilizing a chord that is common to both keys. This method creates a smooth transition between different harmonic areas, enhancing the flow of music. By focusing on a shared chord, composers can effectively pivot from one tonal center to another while maintaining a sense of cohesion in their progressions.
