With advances in technology, video game music has grown to include elements and sounds from other musical styles. While chiptune compositions are still common, game music now includes full orchestral pieces and popular music (having originated during the height of the disco era, styles from which atavistic sounds can be compared). Music in video games can be heard over a game's title screen, menus, as well as during 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 certain achievements
