SingStar is a karaoke game. You need the USB microphones that come bundled with the game in order to play it. What you do is select a song that you want to sing, and it will display the music video and lyrics. In addition to that, it will show bars that represent how high or low the pitch of the notes are. You are scored on how well you match the pitch of the origingal track.
Hope that helps

Random hero pretty much said it all, but I thought I'd add that you can sing the notes at any octave, so long as they are the notes to the song. So, males and females can stick to their respective natural ranges during any song, if they desire.
