Keening

The keening whistle of the tea kettle signaled that the water had boiled.

The keening howls of the wolves echoed through the forest, creating an eerie ambiance.

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

As darkness fell, the keening sound of the loons echoed across the tranquil lake.

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

The keening of the wind echoed through the desolate valley.
