The speaker walks barefoot along a sandy shore under the northern lights, moving gently through the breeze. She covers her mouth and softens a sweet song, as if she wants to keep it private, then lifts her head toward a feeling of closeness, a "resonance" that seems to drift out to where she and someone else belong.
In the second half, the poem shifts to "he," who is far away, hiking hills and lost in quiet thought. He remembers the two of them and looks back past the early rush of infatuation. A cool wind touches him and stirs a melody, and in his mind he sees her wading on that same beach in an Alaskan summer.
The mood is dreamy, tender, and a little wistful. Distance separates the pair, but memory, music, and the shared landscape seem to keep them connected.
