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

The sailor set sail with a keening longing for adventure, eager to explore uncharted waters.

The chilling keening of the banshee sent shivers down the spines of those who heard it.

The keening tone of his voice conveyed the depth of his heartbreak.
