Love this gen! Freedom and Creativity are all I ask for in a technique, this gives me room for both. With a simple snap of the fingers, the user can make anything in the terrain appear as if it was the source of the sound and can add a visual illusion to back this sound up. The genjutsu basically makes anything in the area snap in half. Be it floor, scenery, object... It snaps and end up impairing the opponent in some way. For me, a perfect use of this tech would be to modify the terrain we are fighting on to the point that all we stand on is a make-shift bridge of earth, the bridge hanging high above a vast water source. You "snap" the bridge and make the opponent believe he is falling. Straight after you perform a water style technique from the water source below, making something jump up from it's surface. Whilst the opponent attempts to stop himself 'falling' into the water technique you use a technique that can attack from all directions, leaving the opponent unable to use wind to push themselves out the way of what they think is a water attack from below. Follow up with a kunai and I believe that's game.
Would that work? If they believe the bridge has collapsed and that they are falling, the following water jutsu should work on the way I described, correct?

This is a technique I actually made as a custom for Musical Manipulation users, they play there instrument and send sound chakra into the opponents ear, making said instrument all the target can hear. So as you can imagine, I already have many uses for a jutsu such as this. It's a perfect set-up for a simple kill. The more extravagant the follow up the less likely it'll work IMO. A clone with a kunai and you're dandy.
