Keening

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

The piercing sound of keening could be heard from miles away, signaling the loss of a respected community leader.

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

The sailor set sail with a keening longing for adventure, eager to explore uncharted waters.
