A metallophone is any musical instrument consisting of tuned metal bars which are struck to make sound, usually with a mallet.

Metallophones have been used in music for thousands of years. There are several different types used in Balinese and Javanese gamelan ensembles, including the gendér, gangsa and saron. These instruments have a single row of bars, tuned to the distinctive pelog or slendro scales, or a subset of them. The Western glockenspiel and vibraphone are also metallophones: they have two rows of bars, in an imitation of the piano keyboard, and are tuned to the chromatic scale.

In music of the 20th century and beyond, the word metallophone is sometimes applied specifically to a single row of metal bars suspended over a resonator box. Metallophones tuned to the diatonic scale are often used in schools; Carl Orff used diatonic metallophones in several of his pieces, including his pedagogical Schulwerk. Metallophones with microtonal tunings are used in Iannis Xenakis' Pléïades and in the music of Harry Partch.

Yann Tiersen (born 23 June 1970) is a musician from France. His musical career is split between studio albums, collaborations and film soundtracks with a distinctive sound that is always involved. It can be recognized by its use of a large variety of instruments; primarily the guitar, synthesizer or violin together with instruments like the melodica, xylophone, toy piano, harpsichord, accordion and typewriter.

Tiersen is often mistaken as a composer of soundtracks, himself saying "I'm not a composer and I really don't have a classical background", but his real focus is on touring and studio albums which just happen to often be suitable for film. His most famous soundtrack for the film Amélie was primarily made up of tracks taken from his first two studio albums.

Yann Tiersen was born in Brest in the Finistère département in Brittany in northwestern France, in 1970, into a family of Belgian and Norwegian origins. He started learning piano at the age of four, violin at the age of six, and received classical training at several musical academies, including those in Rennes, Nantes, and Boulogne. In the early 1980s when he was a teenager he was influenced by the punk subculture, and bands like The Stooges and Joy Division. In 1983, at the age of 13, he broke his violin, bought an electric guitar, and formed a rock band. Tiersen was now living in Rennes, and this turned out to be the perfect place for his musical career. In fact, Rennes is home to the three-day music festival Rencontres Trans Musicales, held annually in December, giving him the opportunity to see acts like Nirvana, Einstürzende Neubauten, Nick Cave and the Bad Seeds, The Cramps, Television, and Suicide. A few years later, when his band broke up, Tiersen bought a cheap mixing desk, an 8-track reel-to-reel audio tape recording, and started recording music solo with a synthesizer, a sampler, and a drum machine.
