Keening

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

The old haunted house echoed with the keening cries of unseen spirits.

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

The keening shriek of the fireworks lit up the night sky.

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