The Intonarumori were a family musical instruments invented in 1913 by italian futurist painter and musical composer Luigi Russolo. They were acoustic noise generators that permitted to create and control in dynamic and pitch several different types of noises.Each instrument was made of a wooden parallelepiped sound box with a carton or metal speaker on its front side. The performer turned a crank or pressed an electric button to produce the sound whose pitch was controlled by means of a lever on top of the box. The lever could be moved over a scale in tones, semitones and the intermediate gradations within a range of more than an octave.[…]There were 27 varieties of intonarumori with different names according to the sound produced: howling, thunder, crackling, crumpling, exploding, gurgling, buzzing, hissing and so on.The invention of the intonarumori was the natural outcome of Russolo’s musical theories expounded in his 1913 manifesto L’arte dei rumori(The Art of Noise) in which he presented his ideas about the use of noises in music.
