It is a hugely popular game for PS2 where you play "air guitar" to certain songs and get rated, except that you use a physical guitar-controller.
This is a reference to the original game in Wikipedia
http://en.wikipedia.org/wiki/Guitar_heroIn the XBOX version, you will be able to play air guitar with friends from around the world. That way you can help them improve their technique and really get down and jam to some tunes...

Scoring
50 points are rewarded for every note hit. Chords count as two notes. Each time that 10 consecutive notes are successfully played, the point multiplier increases by one and the points each note is worth is multiplied by that number, up to a maximum four times the base amount — for example, after 10 consecutive notes are played, a single note is 100 (x2) points, a chord is 200 (x2) points. If a note is missed, any active multipliers reset back to x1. Star Power allows the player to temporarily double the score on every note, effectively turning a x4 multiplier into a x8 for its duration.
The final score, along with overall accuracy percentage and longest note streak, are reported at the end of a song. It is not uncommon for a song to contain 400-600 notes or more. A rating of 3, 4, or 5 stars will also be displayed. The amount of stars is based off of the player's score in that song.
