Incidental music

Incidental music:(n) background music in a film, broadcast, etc. (Oxford dictionary)
Three pages of empty musical scores hang from the wall. They seem to be enlargements of the regular pages: their size is 230 x 150 cm each. But the lines are made of news cut out from different local newspapers ( London ) and glued on the sheets following the order of the lines. The news are referred to accidents and murders related to ordinary people. Between the news there is a gap 1 cm long approximately.
A musical piece is composed from theses points or gaps. The sounds are E, G, B, D, F, according to the line where the gaps are. The duration of the sounds depends on the distances between the gaps.
The piece can be listened to through a pair of headphones hanging in front of the pages.
