A prelude, or introduction, serves as an opening section of a literary work, musical composition, or performance. It sets the stage for what follows, providing context, background, or a thematic overview. In literature, a prelude can introduce characters, settings, or key ideas, while in music, it often establishes the mood or tone of the piece. In various forms of art, the prelude helps engage the audience and prepares them for the main content. For example, in a novel, the prelude might hint at the central conflict, while in a symphony, it may feature motifs that reappear throughout the work.
