Keening

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

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

The old television emitted a high-pitched keening noise whenever it was turned on.

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.
