Berlin: Symphony of a Great City [Act 1, Part 1]

"Ruttmann made several abstract film and he refers to them in the beginning with abstract horizontal lines dissolving to rail way tracks. In my view the rest of the film is also abstract. Although we see real people and situations the brilliant editing constantly keeps the film abstract: the situation and the people in a shot are not important, important is the juxtaposition to other shots: is the composition varied enough?. Thus we see a filmic composition (in stead of a musical one) and the subtitle Symphony is just."
