A soldier stands guard at night, and a remembered Bach prelude floods his mind, lifting him out of the dark. The music feels so vivid that the mist seems to clear and the October stars shine more brightly. In that moment, the sentry is not just enduring his watch; he is transfigured by something beautiful.
But the second half turns uneasy. He imagines coming home and finally playing the prelude properly, at a piano, in peacetime. Will the music feel the same? Or will it now drag him back to this half-waking state, to the dull dread of No Man’s Land? The poem leaves the question open. It creates a quiet, haunted mood: beauty and trauma are braided together, and the music he loves may never again be only music.
