Type Sonata

Here I try to type a line from right to left, and a line from left to right through using an Arabic and an English typewriter which move in opposite directions.
Because of the way they are set up next to each other, the two objects move slowly until they meet together in one point.
This action is repeated a few times, until the imperfect “Sonata of lines” are fulfilled.
The result is the production of two scores, Clef de Sol –the lines typed with the right hand-, and Clef de Fa –the lines typed with the left hand.
