Glockenspiel

The glockenspiel (Glocken: bells and Spiel: set) 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, although the xylophone's bars are made of wood, while the glockenspiel's are metal plates or tubes, thus making it a metallophone. The glockenspiel, additionally, is usually smaller and, because of both its material and smaller size, higher in pitch.
