Keening

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

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

The keening shriek of the fireworks lit up the night sky.

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