Keening

The keening screech of the brakes startled the pedestrians on the sidewalk.

The keening of the steam whistle signaled the departure of the train from the platform.

The haunting sound of keening filled the air as the people paid their respects to the fallen soldiers.

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.

The artist's brush moved across the canvas with a keening grace, expressing her deep longing for freedom.
