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

The haunting melody of keening echoed through the ancient ruins, commemorating the souls who had departed.
