"Hrmm," the boy murmured, turning the instrument over (albeit with some difficulty) in his lap, examining it carefully. He didn't quite hear his father, who was twittering on and on about how he got it for cheap in a little shop, and it was called a guitar, and how he just knew the boy would like it.

He jumped at the twang noise it produced, and little Matthias's face lit up with glee and he wiggled his toes in triumph. He plucked again, and again, and then realized you could use a few at the same time! If you pressed down on the long part in made a different sound, even if you pulled on the same string! For the first time in the boy's short, barely yet fifty year life, something sparked.
