Keening

The mournful sound of keening filled the air as the funeral procession made its way to the cemetery.

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

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

The air raid siren's keening pierced through the city, signaling imminent danger.

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