Keening

The old haunted house echoed with the keening cries of unseen spirits.

The singer's voice soared in a beautiful keening note, captivating the audience.

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

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

The chilling keening of the banshee sent shivers down the spines of those who heard it.
