A glockenspiel is a percussion instrument that resembles a xylophone but has metal bars instead of wooden ones. It produces a bell-like sound and is commonly used in orchestras and marching bands. Synonyms for glockenspiels include metallophones, chime bars, and bell kits. A metallophone is a similar instrument with metal bars but is typically larger and has a wider range of notes. Chime bars are smaller versions of glockenspiels that are often used in schools to teach children about music. Bell kits are portable glockenspiels that come with a carrying case and are popular among beginner musicians.
