Keening

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

The old graveyard was filled with the sound of keening voices as mourners gathered to pay their respects.

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

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

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