Keening

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

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

As the funeral procession passed by, the mourners let out keening wails of grief, filling the air with a somber atmosphere.

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.
