The keening whistle of the teapot signaled that the water was boiling.

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

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

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 keening voices of the choir brought tears to the audience's eyes.
