Keening

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

The patient lay in the hospital bed, his keening thoughts consumed by the desire to be healthy again.

As the funeral procession passed by, the sound of keening echoed through the streets.

The old television emitted a high-pitched keening noise whenever it was turned on.

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