Keening

As the fog rolled in, a keening foghorn warned ships of the treacherous rocks ahead.

The widow sat alone in her empty house, keening softly for the husband she had lost.

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.

The women gathered in the cemetery, their voices intertwining in a mournful keening that honored the departed.

The keening voices of the choir brought tears to the audience's eyes.
