Miyamoto San presents Wii Music

Nintendo's Shigeru Miyamoto revealed an ambitious motion-controlled Wii Music title at E3, featuring saxophones, drum kits and more--all controlled by gestures.

This is the drum kit pedals, seriously
At E3 today, Nintendo gave a real-time demo of long-rumored title Wii Music, which will feature gesture-controlled instruments and the new Wii MotionPlus attachment.
Nintendo icon Shigeru Miyamoto told the audience that Nintendo designed Wii Music to allow everyone to experience the joy of performing music.
When players play a saxophone, for example, they hold the controller as they would a real sax. Same for drums, which will use the Wii Balance Board as the kit pedals.
While most music games today require you to press buttons with precise timing to match symbols on screen, Wii Music relies on the gestures and placement of the Wiimote to create songs.
There will be 50 different instruments in all, including drums, piano, guitar, violin and saxophone, all of which you play using the same positions and gestures as the real thing. There was no timing, as in Guitar Hero or Rock Band, as the gestures, button presses, and timing of the player's movements were controlling the action.The software won't grade your performances, Miyamoto said, but it will record them and allow you to create music videos with up to four people.
