Keening

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

The keening wail of the baby echoed through the nursery, causing concern among the caregivers.

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

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.

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.
