The keening cries of the wounded soldier could be heard from the battlefield.

The abandoned dog let out a keening howl, yearning for a loving home.

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

The keening cry of the wolf in the distance sent shivers down their spines.

The wounded animal emitted a haunting keening sound in the distance.
