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 patient lay in the hospital bed, his keening thoughts consumed by the desire to be healthy again.

As the funeral procession passed by, the sound of keening echoed through the streets.

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

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