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

The keening sound of the ambulance pierced through the silence of the night.

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

The keening whistle of the teapot signaled that the water was boiling.

The old television emitted a high-pitched keening noise whenever it was turned on.

The keening tone of his voice conveyed the depth of his heartbreak.
