Answer :
Italian Luigi Russolo was the early twentieth century futurist who built the intonarumori as a way to control everyday sounds, in the way traditional music instruments are controlled.
Intonarumori are innovative musical instruments invented and built by the Italian futurist Luigi Russolo between roughly 1910 and 1930. There were 27 different types of intonarumori built in total, each with its own name.
Each instrument was constructed from a wooden parallelepiped sound box with the a cardboard or metal speaker on the front side.
The sound was produced by the performer turning a crank or pressing an electric button, the pitch of which was controlled by a lever on top of the box. Within a range of more than one octave, the lever could be moved across a scale in tones, semitones, and intermediate gradations.
The majority of Russolo's instruments were destructed when Paris was bombed during WWII.
