Keening

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

The keening cries of the wounded soldier could be heard from the battlefield.

The air raid siren's keening pierced through the city, signaling imminent danger.

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

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

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