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.
