A glockenspiel is a percussion instrument composed of a set of tuned keys arranged in the fashion of the keyboard of a piano. In this way, it is similar to the xylophone; however, the xylophone's bars are made of wood, while the glockenspiel's are metal plates or tubes, thus making it a metallophone.
In German, a carillon is also called a Glockenspiel, while in French, the glockenspiel is often called a carillon. In music scores the glockenspiel is sometimes designated by the Italian term campanelli.
