An evening sky and sea turn into quiet music here. The sunset over the water is described as “coral-music” written on the sea, so the shifting colors feel like a visible song rather than something heard. In the upper sky, the last sunlight becomes gold strings in a harp, and the clouds seem to pluck them, but the melody is “noiseless”—it is made of light and color instead of sound. Then the moon appears, imagined as a young woman dressed in amber, stepping up from the sea into the heavens and dancing as part of an evening ritual.
The speaker feels a calm, wondering reverence. The mood is dreamlike and peaceful, turning an ordinary sunset into something holy and musical. It invites the reader to slow down and watch the sky as a quiet performance.
