My dear Pratella, I submit to your futurist genius these new ideas, and I invite you to discuss them with me. I am not a musician, so that I have no … - Luigi Russolo

My dear Balilla Pratella

This revolution of music is paralleled by the increasing proliferation of machinery sharing in human labor. In the pounding atmosphere of great cities as well as in the formerly silent countryside, machines create today such a large number of varied noises that pure sound, with its littleness and its monotony, now fails to arouse any emotion.

This evolution toward noise-sound is only possible today. The ear of an eighteenth century man never could have withstood the discordant intensity of some of the chords produced by our orchestras (whose performers are three times as numerous); on the other hand our ears rejoice in it, for they are attuned to modern life, rich in all sorts of noises. But our ears far from being satisfied, keep asking for bigger acoustic sensations. However, musical sound is too restricted in the variety and the quality of its tones. Music marks time in this small circle and vainly tries to create a new variety of tones.. .We must break at all cost from this restrictive circle of pure sounds and conquer the infinite variety of noise-sounds.
