Keening

The keening screech of the brakes startled the pedestrians on the sidewalk.

The keening of the steam whistle signaled the departure of the train from the platform.

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.

The haunting sound of keening echoed through the village as news of the tragedy spread.

The keening mother held her child's lifeless body, overcome with grief.
