an audio visual performance
dedicated to Sven Nykvist
cinematographer and director of photography
of most Ingmar Bergman movies.

This performance includes the use
of binaural beat frequencies
and spacialized sound
in dolby surround 5.1

NOTES

It deals with the first of a series of performances that introduces to a public audience the results of a research based on the human perceptive ways and finalized to the induction of a progressive loss of the perception of the chronological time (krònos time), for the medium of a contemporary administration of so that BBF binaural beat frequencies and images, for a "pluridimensional" perception of the moment (Aiòn time).

Likewise to how much it happens for the sight, (every eye records a different image that is combined then by the brain in an single image) the binaural waves are produced with two identical acoustic frequencies to which is applied a difference of phase between the left and the right audio channels. This difference of phase induces the brain to produce a third frequency called "brainwave" (absolutely subjective) that it is the resultant one of a mediation among the two sonorous impulses.

One consolidated scientific literature exists on the survey of the brainwaveses produced by the brain, coherently to the various states that goes from the deep sleep to that of maximum alertness. Those brainwaves are objectively recordable and measurable with a simple electroencephalogram: what is still field of experimentation it is the abstract that, for the medium of the BBF, the brain can be induced to produce a brainwave submitting to the same kind of frequency.

For instance: administering to a listener a frequency that corresponds to the so-called state of "lucid dreaming", slowly his brain would begin to produce the same kind of frequency (brainwave), with a process very similar to that defined in acoustic field "resonance for simpathy". As when picking a single string in a Sitar a resonance of all the others is obtained. The result, obviously is not mechanic, or automatic: our brain is a lot more complex than the also complicated and difficult Indian musical tool. Good part depends from the wish and from the predisposition of whom submits to BBF.

The operation unfolded in the carrying out of Aiòn#oo1 is the contemporarily uses of different perceptive inputs.
The musical audio traces, mixed with BBF, are spacialized in real time in a dolby surround 5.1 diffusion : this audio system adds to the traditional stereo audio source (frontal, left and right channel), two back sources, a central one and a sub-frequency one. Differently to what happens in home-teathre or in the cinema rooms endowed with this system, in Aiòn#oo1 all the audio sources have the same importance, the sub-frequencies are used to the limit of the human audible range (infra-sound) and the audio channels movement (spacialization) it is finalized to produce a three-dimensional sonorous perception.

The black and white images projected in the main screen, are a tribute to the director of photograpy Sven Nikvyst recently disappeared. They have been extrapolated from cinema-works realized in collaboration with Ingmar Bergman during the sixties. The images have been de-contestualized and re-contestualized in a new assemblage and editing coherent to the composition of the musical traces and the audio used during the performance. The video have been climbed on to the audio that is born before the images, reversing the traditional composition process for a soundtrack .

In the second screen a color strobo pulsation is projected, an it proceeds in sinchro to the diffusion of the BBF.

For these considerations Aiòn#oo1 can be defined as an "interactive" performance in the deepest sense of the term: the whole used media are understood to act in inductive sense for a perception more close to the limbic one rather than a rational or encoded. Every single element of the public is invited to listen to the really "internal concert/performance" as active protagonist and not passive.

This kind of perception is free from the krònos time and it is absorbed in to the Aiòn.
