The art of noise

Russolo differentiates between noise and silence by saying that noise is something that is man-made, whereas silence is everything that is not- such as nature. Noise arose from the invention of machines, with their unnatural attributes, it was a result of the machinery, rather than the original intention. Sound was something man was conscious of- a string stretched to make a sound, rather than a string stretched and then sound being an afterthought. Sound was mysterious and rare, while noise was just an outcome of another thing. Russolo's explanation makes me believe that he thinks "silence" is something only achieved by the ancient and the natural. I personally don't think that silence exists on Earth. With atmosphere, there is sound, and even the most minute sound can be heard amidst what one may think to be silence. Even if a person were to be completely still, the pulsing of their heart is making a small sound. In an open field without civilization, the small whirr of a breeze can be heard. Even in nature, there can never be complete silence. There can only be attempts at it. Russolo sees current music as boring, with music competing against each other with the same instruments and methods of altering sound-noise. He thinks that the art of noise must not limit itself to imitative reproduction, and says in order to avoid this that musicians must manipulate fantastic juxtapositions of varied tones and rhythms, combining them according to our imagination.
