do you see the two arrows scrolling down the screen through the two boxes
if you do and you have and xbox 360 controller
you have to time the arrows going through the boxes using the left and right triggers on the xbox 360 controller either left or right or both at the same time you will be told if your timing is good . perfect or whatever
if you time it right for most of the tune you'll pass
if you already know this then I cannot help you
Good Luck
