Betsy has to play her xylophone in the school recital but she has to get her hair dressed and does not want to take her xylophone to the hairdresser. She entrusts George and Steve to get the xylophone to the school. Unfortunately when George knocks the xylophone over he must put it back together. He remembers how the notes, when played in order, sound like they are climbing stairs. But it seems like no matter how he sets up the bars, he can't get them in order. He realizes he needs to count in order from one to set up the xylophone properly. But George cannot count past 12 and the xylophone has more pieces than that.
