The Art of Noise by Luigi Russolo (.pdf)
Some will object that noise is necessarily unpleasant to the ear. The objection is futile, and I don’t intend to refute it, to enumerate all the delicate noises that give pleasant sensations. To convince you of the surprising variety of noises, I will mention thunder, wind, cascades, rivers, streams, leaves, a horse trotting away, the starts and jumps of a carriage on the pavement, the white solemn breathing of a city at night, all the noises made by feline and domestic animals and all those man’s mouth can make without talking or singing.
