The theme song of "Pirates of the Caribbean" is quite familiar to movie lovers. As a movie fan, the guiding teacher modified the orchestra song and had the Children Orchestra play the song. Since the instrument kinds, arrangements, tones and members' music literacy are different between the orchestra and the rhythm band, the teacher made a great effort in delegating the musical instruments. To have these young little members create the magnificent power of the orchestra with their children's musical instruments is a process of challenge and surprise.
