A
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; 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.
