韵律 (Rhythm) refers to the pattern of sounds and silences in music and poetry. It is created by the arrangement of beats, which can vary in duration and intensity. Rhythm helps to establish the flow and structure of a piece, making it more engaging and memorable. In music, rhythm is often marked by a steady beat, which can be divided into measures. In poetry, rhythm can be achieved through the arrangement of stressed and unstressed syllables. Both forms rely on meter and tempo to create a sense of movement and emotion.
