The video game SingStar ’90 is a karaoke experience that includes popular songs from the nineties.
The accuracy of one’s singing, measured by how well one can maintain pitch, determines how many points one receives in this game. It makes no difference if you switch octaves amid the song or what words you are singing (it doesn’t have word recognition). Therefore, your singing is evaluated based on how well you can hit the right note at the right moment.
