Chiptune, also called 8-bit music, is a style of electronic music and musical subculture made using the programmable sound generator (PSG) sound chips or synthesizers in vintage arcade machines, computers and video game consoles. The term is commonly used to refer to tracker format music using extremely basic and small samples that an old computer or console could produce, as well as music that combines PSG sounds with modern musical styles. It has been described as "an interpretation of many genres". Any existing song can be arranged in a chiptune style. It can be defined by choice of instrument, by timbre more than specific style elements.
