The correct answer is Option (4) → Prelude

A prelude is a short piece of music that introduces a longer piece; more widely, any event that comes before and leads to a more important one. It comes from the Latin prae (before) + ludere (to play).
Example: The orchestra began with a short prelude before the opera.

Why the Other Options are Incorrect?

Option 1: Epilogue — Incorrect. An epilogue is a section at the end of a book, play or film that rounds it off; it comes at the end, not at the beginning, and it is not music.
Example: The epilogue tells us what happened to the characters ten years later.

Option 2: Epitome — Incorrect. Epitome means a perfect example of a quality or type; it has nothing to do with music.
Example: She is the epitome of patience.

Option 3: Prologue — Incorrect. A prologue is an introduction to a play, poem or book; it is a piece of writing or speech, not of music.
Example: The prologue of the play is spoken by a narrator.
