Keening

The keening stench of decay emanated from the garbage dumpster, making it difficult to pass by.

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

The widow sat alone in her empty house, keening softly for the husband she had lost.

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

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