Rhythm game
Rhythm game, or rhythm action, is a subgenre of action game that challenges a player's sense of rhythm, and includes dance games such as Dance Dance Revolution and other music-based games such as Donkey Konga and Guitar Hero. These games challenge the player to press the right button at the right time: the screen shows which button the player should press next, and the game awards points for being on the beat. The genre also includes games that measure both rhythm and pitch, in order to test a player's singing ability. In addition to rhythm, some games may challenge the player to control their volume by measuring how hard they press each button. While songs can be sight read without having performed them before, players usually practice to master more difficult songs and settings. Other rhythm games offer a challenge similar to that of Simon says, where the player must watch, remember, and repeat complex sequences of button-presses.
