Keening

As the fog rolled in, a keening foghorn warned ships of the treacherous rocks ahead.

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

The old graveyard was filled with the sound of keening voices as mourners gathered to pay their respects.

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

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