The glockenspiel is a percussion instrument with a set of tuned metal plates, laid out like a piano keyboard, and struck with a pair of small hammers.  The term is German, meaning play bells (Glocken = bells,  spiel = play).

The glockenspiel originates from Indonesia, from where it was brought into the Netherlands in the 1650s, and from there it spread over Europe. It was used by Handel in 1739.
