Geräuschmusik again ...

Lichtenberg

'It is easy to construct a landscape out of a mass of disorderly lines, but disorderly sounds cannot be made into music.'

'Everything grows more refined and polished: music was once noise, satire was once lampoon, and where we nowadays say Please excuse me, in the old days we cuffed his head.'

— G.C. Lichtenberg (Sudelbücher, A.40, D.83.)
