Keening

The keening stench of decay emanated from the garbage dumpster, making it difficult to pass by.

The keening notes of the bagpipes resonated through the air during the memorial ceremony.

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

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

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