Keening

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

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

The old man sat by the grave, keening softly for his departed wife.

The haunting sound of keening filled the air as the people paid their respects to the fallen soldiers.

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