The keyboard glockenspiel (French: jeu de timbre) or organ glockenspiel is an instrument consisting of a glockenspiel operated by a piano keyboard. It was first used by George Frideric Handel in the oratorio Saul (1739). It was also used in the 1739 revivals of his Il Trionfo del Tempo and Acis and Galatea, and the next year in L'Allegro, il Penseroso ed il Moderato. Half a century later, Wolfgang Amadeus Mozart employed a strumento d'acciaio in The Magic Flute (1791) to represent Papageno's magic bells. It is now considered proven that Mozart meant a keyboard glockenspiel.
From the 19th century onwards, the keyboard glockenspiel fell into the background due to the introduction of the celesta in 1886, which, due to its larger range and more modern construction, could also play more difficult glockenspiel parts.[9] In contrast to the very soft sound of the celesta (produced by the felt hammers of the playing mechanism), the historical keyboard glockenspiel had a very clear, metallic sound. Its sound plates were struck with steel or hard plastic clappers. It had no sound-enhancing soundboard and usually had a range of 2 to 2.5 octaves. There are also a smaller number of historical instruments with a range of 3 1/3 octaves (C5–E8).
