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.

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

The haunting melody of the keening bagpipes played at the memorial service brought a sense of solemnity to the occasion.

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