Keening

The old haunted house echoed with the keening cries of unseen spirits.

The mournful keening of the women in black veils set a somber tone for the entire funeral procession.

The keening smell of rotten eggs filled the kitchen, indicating a gas leak.

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.
