Keening

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

The old graveyard was filled with the sound of keening voices as mourners gathered to pay their respects.

The mourners joined in a collective keening, their voices blending in a sorrowful chorus that echoed through the valley.

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.

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