Keening

The keening stench of decay emanated from the garbage dumpster, making it difficult to pass by.

The refugee glanced back at his war-torn homeland with keening eyes, filled with longing for a peaceful life.

The young child stood by the graveside, keening for his pet dog that had passed away.

The keening shriek of the fireworks lit up the night sky.

The keening voices of the choir brought tears to the audience's eyes.
