"Percussions" cymbals, bells, xylophone, chimes, and drums "Stray types" organ, music box, and piano In his book Cube Route (2003), Anthony explains that unicorns sound their instruments through their horns. The reclusive sea-unicorn (commonly known as the "narwhal") similarly transmits acoustic signals through its spirally twisted tusk. "When a captive bull narwhal vocalized, strong vibrations corresponding to the sound could be felt running down the tusk" (Ted Kerasote, Bloodties: Nature, Culture, and the Hunt, 1994). Unicorns' musical tones can actually form common words. In Juxtaposition (1982), Anthony says that unicorns "almost speak in musical notes, making them sound like yes, no, maybe, and assorted other words." Note that these examples of unicorn vocabulary convey the full range of opinions, and varying degrees of decisiveness, of which these complex creatures are capable. Accounts of unicorns' orchestral voices in literature include: The unicorn shuddered, sending out music that filled Emily's head with fragmented and off-key chords and words that were little more than broken cries. -- Rachel Roberts, Avalon: Web of Magic 4: Secret of the Unicorn (2002)
