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 keening aroma of freshly baked bread wafted through the bakery.

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

The traveler explored foreign lands with a keening spirit, constantly seeking new experiences.

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