Check out this automaton which plays When the Saints Go Marching In on the xylophone...or is that a glockenspiel because they are metal plates? In any case, the machine design and fabrication are outstanding!
OK...I did some quick research. It is a glockenspiel. Here is the word from Wikipedia:
A glockenspiel (German pronunciation: [ˈɡlɔkənˌʃpiːl], glocken:bells and spiel: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. In German, a carillon is also called a Glockenspiel, while in French, the glockenspiel is often called a carillon.
Show above is the GP Percussion Bell Kit. It looks like a good deal because it comes with the 30 note glockenspiel as well as a heavy duty stand, practice pad, beaters, sticks, and nylon carrying case.
It's nearly back-to-school time. If you order any instruments from Amazon, consider doing via the link you see here for Musical Instruments. Thanks!
