Keening

The mournful sound of keening filled the air as the funeral procession made its way to the cemetery.

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

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

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

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