The story is told of a family of mice that lived inside an upright piano. For generations, the mice were impressed by the music that filled their world. It began at sunrise each day, and after pausing for a time in the heat of the day, picked up again as the sun set. Over time, the mice concluded that the music must be coming from a Great Player whom they could not see. They drew comfort that this Great Player was there, and was making his presence known to them.
