Dear Balilla Pratella, great Futurist composer,

In Rome, in the Costanzi Theatre, packed to capacity, while I was listening to the orchestral performance of your overwhelming Futurist music, with my Futurist friends, Marinetti, Boccioni, Carrà, Balla, Soffici, Papini and Cavacchioli, a new art came into my mind which only you can create, the Art of Noises, the logical consequence of your marvelous innovations.

Ancient life was all silence. In the nineteenth century, with the invention of the machine, Noise was born. Today, Noise triumphs and reigns supreme over the sensibility of men. For many centuries life went by in silence, or at most in muted tones. The strongest noises which interrupted this silence were not intense or prolonged or varied. If we overlook such exceptional movements as earthquakes, hurricanes, storms, avalanches and waterfalls, nature is silent.

Amidst this dearth of noises, the first sounds that man drew from a pieced reed or streched string were regarded with amazement as new and marvelous things. Primitive races attributed sound to the gods; it was considered sacred and reserved for priests, who used it to enrich the mystery of their rites.

And so was born the concept of sound as a thing in itself, distinct and independent of life, and the result was music, a fantastic world superimposed on the real one, an inviolatable and sacred world. It is easy to understand how such a concept of music resulted inevitable in the hindering of its progress by comparison with the other arts. The Greeks themselves, with their musical theories calculated mathematically by Pythagoras and according to which only a few consonant intervals could be used, limited the field of music considerably, rendering harmony, of which they were unaware, impossible.

The Middle Ages, with the development and modification of the Greek tetrachordal system, with the Gregorian chant and popular songs, enriched the art of music, but continued to consider sound in its development in time, a restricted notion, but one which lasted many centuries, and which still can be found in the Flemish contrapuntalists’ most complicated polyphonies.

The chord did not exist, the development of the various parts was not subornated to the chord that these parts put together could produce; the conception of the parts was horizontal not vertical. The desire, search, and taste for a simultaneous union of different sounds, that is for the chord (complex sound), were gradually made manifest, passing from the consonant perfect chord with a few passing dissonances, to the complicated and persistent dissonances that characterize contemporary music.

At first the art of music sought purity, limpidity and sweetness of sound. Then different sounds were amalgamated, care being taken, however, to caress the ear with gentle harmonies. Today music, as it becomes continually more complicated, strives to amalgamate the most dissonant, strange and harsh sounds. In this way we come ever closer to noise-sound.

This musical evolution is paralleled by the multipication of machines, which collaborate with man on every front. Not only in the roaring atmosphere of major cities, but in the country too, which until yesterday was totally silent, the machine today has created such a variety and rivalry of noises that pure sound, in its exiguity and monotony, no longer arouses any feeling.

To excite and exalt our sensibilities, music developed towards the most complex polyphony and the maximum variety, seeking the most complicated successions of dissonant chords and vaguely preparing the creation of musical noise. This evolution towards “noise sound” was not possible before now. The ear of an eighteenth-century man could never have endured the discordant intensity of certain chords produced by our orchestras (whose members have trebled in number since then). To our ears, on the other hand, they sound pleasant, since our hearing has already been educated by modern life, so teeming with variegated noises. But our ears are not satisfied merely with this, and demand an abundance of acoustic emotions.

On the other hand, musical sound is too limited in its qualitative variety of tones. The most complex orchestras boil down to four or five types of instrument, varying in timber: instruments played by bow or plucking, by blowing into metal or wood, and by percussion. And so modern music goes round in this small circle, struggling in vain to create new ranges of tones.

This limited circle of pure sounds must be broken, and the infinite variety of “noise-sound” conquered.

Besides, everyone will acknowledge that all musical sound carries with it a development of sensations that are already familiar and exhausted, and which predispose the listener to boredom in spite of the efforts of all the innovatory musicians. We Futurists have deeply loved and enjoyed the harmonies of the great masters. For many years Beethoven and Wagner shook our nerves and hearts. Now we are satiated and we find far more enjoyment in the combination of the noises of trams, backfiring motors, carriages and bawling crowds than in rehearsing, for example, the “Eroica” or the “Pastoral”.

We cannot see that enormous apparatus of force that the modern orchestra represents without feeling the most profound and total disillusion at the paltry acoustic results. Do you know of any sight more ridiculous than that of twenty men furiously bent on the redoubling the mewing of a violin? All this will naturally make the music-lovers scream, and will perhaps enliven the sleepy atmosphere of concert halls. Let us now, as Futurists, enter one of these hospitals for anaemic sounds. There: the first bar brings the boredom of familiarity to your ear and anticipates the boredom of the bar to follow. Let us relish, from bar to bar, two or three varieties of genuine boredom, waiting all the while for the extraordinary sensation that never comes.

Meanwhile a repugnant mixture is concocted from monotonous sensations and the idiotic religious emotion of listeners buddhistically drunk with repeating for the nth time their more or less snobbish or second-hand ecstasy.

Away! Let us break out since we cannot much longer restrain our desire to create finally a new musical reality, with a generous distribution of resonant slaps in the face, discarding violins, pianos, double-basses and plainitive organs. Let us break out!

It’s no good objecting that noises are exclusively loud and disagreeable to the ear.

It seems pointless to enumerate all the graceful and delicate noises that afford pleasant sensations.

To convince ourselves of the amazing variety of noises, it is enough to think of the rumble of thunder, the whistle of the wind, the roar of a waterfall, the gurgling of a brook, the rustling of leaves, the clatter of a trotting horse as it draws into the distance, the lurching jolts of a cart on pavings, and of the generous, solemn, white breathing of a nocturnal city; of all the noises made by wild and domestic animals, and of all those that can be made by the mouth of man without resorting to speaking or singing.

Let us cross a great modern capital with our ears more alert than our eyes, and we will get enjoyment from distinguishing the eddying of water, air and gas in metal pipes, the grumbling of noises that breathe and pulse with indisputable animality, the palpitation of valves, the coming and going of pistons, the howl of mechanical saws, the jolting of a tram on its rails, the cracking of whips, the flapping of curtains and flags. We enjoy creating mental orchestrations of the crashing down of metal shop blinds, slamming doors, the hubbub and shuffling of crowds, the variety of din, from stations, railways, iron foundries, spinning wheels, printing works, electric power stations and underground railways.

Nor should the newest noises of modern war be forgotten. Recently, the poet Marinetti, in a letter from the trenches of Adrianopolis, described to me with marvelous free words the orchestra of a great battle:
