        Suddenly, inspiration struck.  Before they sung the piece in Draconic, they had learned a spell to lower their voices, and—since everypony wasn’t a unicorn—the voices of others.  It required minimal effort to cast, and would remain in effect until deliberately dispelled.  Twilight and she had been discussing the possibility of such a spell, but she’d been concentrating so hard on scholarly spells, this one had never occurred to her.  If she used it, she could drop her voice two octaves into his vocal range, and he might have better luck understanding.  It was by no means a permanent solution—if he ever went to Equestria, it was unreasonable to expect that everypony would alter their voice just to speak with him—but as long as he could correctly pronounce words, he would be understood.  Like most creatures, ponies’ aural range was much broader than their vocal.
