Keening

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

The old haunted house echoed with the keening cries of unseen spirits.

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

The mournful keening of the women in black veils set a somber tone for the entire funeral procession.

The widow sat alone in her empty house, keening softly for the husband she had lost.
