Sheet Music has always been displayed in a flat, 2D way. All notes that occur at the same time are vertically aligned, forming a sort of table (score) that is easy to read. However, 2D is not the way music is perceived. Bass notes tend to be less perceptible, but remains audible for much longer, just like if they were at the background, in the same way that mountains and clouds are visible longer through the train window than trees at the rail side.

The Parallax Score mode search to represent this sonorous perception in a graphical way. As the music is played, each staff is displaced horizontally at a different speed. Notes from different staves occurring at the same time are only vertically aligned at the exact moment they are pitched, when harmony is created.
