A glockenspiel [German Glocken (bells) + spielen (to play)] 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. The glockenspiel, moreover, is usually smaller and higher in pitch.
