In making a film you're trying to get the most interesting orchestration of all these elements, which, like music, need to be harmonic yet contradictory. If they're completely contradictory, then there's chaos. It's like when instruments are tuning up before a performance, you can't make anything coherent out of it. It's a fascinating, evocative sound, but only for about fifteen seconds. If, on the other hand, all the instruments play the same notes—if they're too harmonic, in other words—yes, there's coherence, but I'm bored after a few minutes. Just as bored as with the chaos of tuning up.
