This piece is made with a software that turns a graphic score into music. Like in other graphic software, different layers can be superposed.
In this piece the first layer contains a straight line and the second another one, that intends to match exactly the first one. The third layer contains the same attempt of covering the first line, extensively unsuccessful, like the previous. In the end five superposed lines are converted into the sound of piano.
As the piano is a percussion instrument, what actually sounds are the failed attempts of matching, the deviation from the original line. (Dresden, 2001)
