White, Pink, Red, Blue, violet and grey Noise

"white noise is a random signal (or process) with a flat power spectral density. The signal's power spectral density has equal power in any band, at any centre frequency, having a given bandwidth. White noise is considered analogous to white light which contains all frequencies".
(from wikipedia)

Noise, like painting, can be also defined by colours. Even the electronics components have colours. The electronic circuit becomes like multicolour city. The components are the buildings and the streets are the connection between the buildings. The noisy property of the sound is generated through this crowd and imaginary space, which is identified also by colours.

Intonarumori - 1913 (The beauty of noise)

There is no beauty in noise. And so what's the point of make it. Noise is, by vocabulary definition, the auditory experience of sound that lacks musical quality. I have got another one which is more practical: an electric disturbance in a communications system that interferes with or prevents reception of a signal or of information, as the buzz on a telephone or snow on a television screen.
And so noise is somehow the end of the communication, the end of the words and the beginning of a different sort of “communication”. In the image above, Luigi Russolo is playing his noisy machine called "intona rumori" literally noise intoners. Luigi Russolo can be defined as a precursor of the electronic music.

Max Neuhaus, John Cage, Edgar Varese

Our perception of space depends as much on what we hear as on what we see. (Max Neuhaus)

I have nothing to say And I am saying it And that is poetry.” (John Cage)

I was not influenced by composers as much as by natural objects and physical phenomena.
(Edgard Varese)

Infiltration-homogen for Grand Piano by Joseph Beuys

Joseph Beuys as other members of the fluxus movement often uses pianos for his works.
But, unlike John Cage who uses the piano has a sound source, Beuys transform the piano in a silent sculpture covering it with felts, protecting the piano against the outside world influence.

Circuit Bending Performance

What is circuit bending?
Definition from wikipedia:
"Circuit bending is the creative short-circuiting of devices such as low voltage, battery-powered guitar effects, children's toys and small synthesizers to create new musical instruments and sound generators. Emphasizing spontaneity and randomness, the techniques of circuit bending have been commonly associated with noise music, though many more conventional contemporary musicians and musical groups have been known to experiment with "bent" instruments".

In this circuit bending performance the performers are randomly welding components in order to generate unexpected noises, becoming also a visual experience.
