Keening

As the fog rolled in, a keening foghorn warned ships of the treacherous rocks ahead.

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

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

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

The injured bird emitted a keening cry, signaling its distress.

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