The term “concord” in literature spans a rich spectrum of meanings—from the harmonious blending of musical tones, as seen when the vibrations of notes form a simple ratio [1], to the emblem of social and political unity that holds families and whole states together [2, 3, 4]. Classical and political writings often invoke “concord” to signify the well-ordered peace essential for civic life, as noted by Augustine and others who describe temples or decrees meant to secure collective harmony [5, 6, 7]. At the same time, literary works dramatize the tension between concord and discord, using the term to evoke moments where unity must overcome conflict or where the absence of concord leads directly to strife [8, 9]. Even in more modern settings, “concord” is rendered in metaphors that celebrate regional identity or personal unity, as when a town or a cherished friendship is linked to its name or spirit [10, 11].
