Keening

The keening cries of the bereaved could be heard at the gravesite.

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

The eerie keening of the ghostly apparition sent shivers down their spines.

The mourners' keening filled the air as they bid farewell to their beloved friend.

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