Modulation

Definition

Modulation is the process of changing from one key to another within a piece of music, which plays a crucial role in shaping the emotional and structural narrative of a composition. This technique enhances the tension and release in music, creating contrast and development as composers explore different tonalities. It also supports the overall framework of functional harmony and is integral to forms like the sonata, reflecting the evolution of musical styles and practices.
