Video game music

Video game music (or VGM) is the soundtrack that accompanies video games. Early video game music was once limited to sounds of early sound chips, such as programmable sound generators (PSG) or FM synthesis chips. These limitations have led to the style of music known as chiptune, which became the sound of the first video games. With technological advances, video game music has grown to include a wider range of sounds. Players can hear music in video games over a game's title screen, menus, and gameplay. Game soundtracks can also change depending on a player's actions or situation, such as indicating missed actions in rhythm games, informing the player they are in a dangerous situation, or rewarding them for specific achievements. Video game music can be one of two kinds: original or licensed. The popularity of video game music has created education and job opportunities, generated awards, and led video game soundtracks to be commercially sold and performed in concerts. Chiptune and Music Macro LanguageAt the time video games had emerged as a popular form of entertainment in the late 1970s, music was stored on physical media in analog waveforms such as compact cassettes and phonograph records. Such components were expensive and prone to breakage under heavy use, making them less than ideal for use in an arcade cabinet, though in rare cases such as Journey, they were used. A more affordable method of having music in a video game was to use digital means, where a specific computer chip would change electrical impulses from computer code into analog sound waves on the fly for output on a speaker. Sound effects for the games were also generated in this fashion. An early example of such an approach to video game music was the opening chiptune in Tomohiro Nishikado's Gun Fight (1975). While this allowed for the inclusion of music in early arcade video games, it was usually monophonic, looped or used sparingly between stages or at the start of a new game, such as the Namco titles Pac-Man (1980) composed by Toshio Kai or Pole Position (1982) composed by Nobuyuki Ohnogi.
