Keening

The keening sound of the ambulance pierced through the silence of the night.

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

The keening aroma of freshly baked bread wafted through the bakery.

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

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