Listen for a sweet, piercing voice. Lost in the hypnotic eyes of the unicorn, he heard a sweet and primeval voice in the air. -- Ben Okri, Astonishing the Gods (1999) Mary Stanton records hearing the singular voices of unicorns frolicking on a riverbank: And the sounds -- the high sweet voices of the unicorn foals who played by the Imperial River, the singing of two mares in a happy duet, the bell-like splash of water! The sounds were like nothing she had heard before. (Night of the Shifter's Moon, 2000) L. Frank Baum is less poetic in his description of a unicorn's "high, squeaky voice" (The Magic of Oz, 1919). In any case, unicorns' pristine, piercing voices seem to hang in the air. They may be reminiscent of: squeals of delight spears of light gliding through the darkness air escaping a balloon sleigh bells
