Keening

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

The old man sat by the grave, keening softly for his departed wife.

The haunting sound of keening filled the air as the people paid their respects to the fallen soldiers.

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

The character in the horror movie let out a keening scream that sent chills down the audience's spine.

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