Keening

The keening sound of the ambulance pierced through the silence of the night.

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.

As the funeral procession passed by, the sound of keening echoed through the streets.

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