"Prélude" is a musical term that refers to a short piece of music that serves as an introduction to a larger work, such as an opera or a suite. It is often characterized by its free form and expressive style, allowing composers to set the mood for what follows. Many composers, including Johann Sebastian Bach and Claude Debussy, have written famous préludes that showcase their unique musical ideas. In literature, "Prélude" can also refer to a preface or introductory section of a book or poem. This part often provides context or background information, preparing the reader for the main content. Notable works, such as Charles Dickens's "David Copperfield," include préludes that enhance the reader's understanding of the story's themes and characters.
