In my Art Electronic exhibition, ELECTROURBS, 1979, at N.O. Space, In Porto Alegre and after in 1982, at Funarte, Galeria Sergio Milliet I used one electronic stetoscope to amplify the heart beats for medical diagnostics, and creatively I intended to create a heart sound landscape inside the white cube. In the late artistic setup based on this theme, the use of thar stetoscope was influenced by the routine of medical doctors in my family ( I worked together with my husband and two vascular surgeons, my brothers). They had such device to amplify the signals for better diagnostics, in case of too much noice by the children and to amplify the heart signals inside the veines ) . Poetically, I translated the possibility to make the sounds full the empty of the space by creating a heart landscape.
Technically, I added the osciloscope connected to amplifiers and used the flux of electrical waves to visualize the cardiac sound traces inside the art space. The cube was transformed into a cardiac sonic landscape. And the sound was also translated into lines and graphic flux by using a oscilloscope which allowe prints translating the sound in forms when recording the cardiac sounds waves.
The artwork was placed in the hybrid territory of performance, prints and installation which included the visitant into the piece. Visitants were invited to seat in a black Model Thonet chair, balance chair, the artwork allowed to heard and record the visitant blood flow. In 1982, RJ, the scenario for such intimate situation was also composed by a neon graphic vein in the ceiling. The cardiac sounds emitted by the stetoscope were transformed into time-varying electrical voltages, corresponding to sound pressure visualized into a transduccion of heart electrical waves. These electric voltages were displayed at the oscilloscope, and the viewer could visualize the waveform of the heart sounds which could also be hear simultaneously with the displayed waveform. Additionally, red neon lights installed in the environment setup, contrasted with the heart beatings, as the sounds of blood flow could be heard synchronically with the heart beatings. The reception of this work by the public was very positive, and many people reported that they felt great seeing their hearts in connection with the sounds and the ones mutation in the oscilloscope display.
In terms of enactive systems, my recent research, this piece announced topics of the inserted organism in the environmnent and technological apparatus mutual exchanges. All these topics are enhanced in my actual artwork related to embodiments and enactive sytems in body mutal exchanges of living systems, physiology and aesthetic appeal.
