Keening

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

The abandoned puppy let out a keening howl, desperately yearning for someone to rescue it.

The wounded animal emitted a keening cry, pleading for help.

The keening howls of the wolf pierced the silence of the night.

The haunting melody of the keening bagpipes played at the memorial service brought a sense of solemnity to the occasion.
