Keening

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

The ancient ritual involved participants keening together to honor their ancestors.

The keening shriek of the fireworks lit up the night sky.

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