Direct modulation

Definition

Direct modulation is a technique in music that involves a sudden change from one key to another without any preparatory chords or transition. This method creates an immediate shift in tonality, often resulting in heightened emotional impact and surprise within the piece. Unlike other modulation techniques that use pivot chords or gradual transitions, direct modulation can provide a more striking contrast between sections.
