Keening

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

The old graveyard was filled with the sound of keening voices as mourners gathered to pay their respects.

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

The young child stood by the graveside, keening for his pet dog that had passed away.

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

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