The word “prelude” has been employed by authors to denote both a literal introduction—often with a musical connotation—and a metaphorical harbinger of what is to come. In many literary works, such as those by Proust ([1], [2], [3]) and Hugo ([4], [5], [6], [7], [8]), it evokes the idea of a musical opening—a piece played before the main performance. Meanwhile, writers like Addison ([9]), Shelley ([10], [11], [12]), and Verne ([13]) use “prelude” to suggest an event or circumstance that foreshadows a significant, often transformative, occurrence. Philosophical texts by Plato ([14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25]) further extend its usage, employing the term to indicate preliminary stages of intellectual or societal development. In this way, “prelude” functions broadly to prepare readers for the thematic, emotional, or narrative shifts that lie ahead, whether through the tangible medium of sound or the metaphorical promise of events to unfold.
