The glockenspiel (German, "set of bells" or "play-bells", also known as orchestra bells and, in its portable form, bell lira or bell lyre) is a musical instrument in the percussion family. It is similar to the xylophone, in that it has tuned bars laid out in a fashion resembling a piano keyboard. The xylophone's bars are wooden, while the glockenspiel's are metal, thus making it a metallophone.
In Germany, a carillon is also called a Glockenspiel.
The glockenspiel, moreover, is much smaller and higher in pitch. When used in a marching or military band, the bars are sometimes mounted in a portable case and held vertically. In orchestral use, the bars are mounted horizontally. A pair of hard unwrapped mallets, made of rubber, plastic, or metal, are generally used to strike the bars, although if laid out horizontally, a keyboard may be attached to the instrument to allow chords to be more easily played.
The glockenspiel's range is limited to the upper register, and usually covers about two and a half to three octaves. The glockenspiel is a transposing instrument; its parts are written two octaves below concert pitch. When struck, the bars give a very pure, bell-like sound.
One classical piece where such an instrument is used is Mozart's Die Zauberflöte (although the part has most often been played with a celesta in modern times). A modern example of the glockenspiel is Steve Reich's 1974 composition Drumming, in which the glockenspiel becomes a major instrument in the 3rd and 4th movements.
Other instruments which work on the same struck-bar principle as the glockenspiel include the marimba and the vibraphone. There are also many glockenspiel-like instruments in Indonesian gamelan ensembles.
