A tightly wrought narrative poem stages a nocturnal encounter in which a bereaved speaker is visited by a persistent, enigmatic bird whose recurring refrain amplifies the speaker’s sorrow and obsession, the verse relying on musical repetition, vivid atmosphere, and steadily intensifying mood. Paired with the poem is a candid prose exposition that claims to reconstruct the compositional choices behind the verse: the deliberate selection of a single strong effect, a strict limit of length suitable for one sitting, the primacy of beauty and unity, and a step-by-step, almost mathematical method for achieving the intended emotional outcome, while also inviting skepticism about the account’s literal accuracy.
