Keening

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

The refugee glanced back at his war-torn homeland with keening eyes, filled with longing for a peaceful life.

The mourners joined in a collective keening, their voices blending in a sorrowful chorus that echoed through the valley.

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

The chilling keening of the banshee sent shivers down the spines of those who heard it.
