The poem follows a woman dancing while snow falls around her, seen through the eyes of someone who can't look away. The speaker is clearly captivated. Her hair is compared to a flame, and her smile is strong enough to "melt away" the cold, so she seems to bring warmth into a freezing scene. Her eyes are likened to the waters of Destin, which suggests something bright and open, and the line "calm but never tamed" paints her as both gentle and fiercely free.
The middle of the poem admits a small flaw: some steps are misplaced and she stumbles when the music changes. But she recovers, and that makes her more impressive rather than less. Then the snow stops, the lights fade, and applause ends what the speaker calls an "infinite play." The mood is quiet and admiring, with a touch of wistfulness, since the performance felt endless while it lasted but still has to finish.
