Variations on Harmonic Tremor is the new solo exhibition of musician and multimedia artist Yuval Avital, produced by Cusumano Masterpieces and sponsored by'National Institute of Geophysics and Volcanology (INGV). Thursday 16 November the vernissage of the exhibition itinerary, open until 20 December, at the Leonardo da Vinci National Museum of Science and Technology in Milan. A journey-investigation conducted by the multifaceted Avital between 2016 and 2017 in the territory of Etna, the largest active volcano in Europe.
To supply part of the materials used in the Icon-sound polyptych 4 parallel projections and loudspeakers, the Etna Observatory (OE) of the INGV of Catania. In particular, the data of the volcanic tremor in numerical format, then transformed into text files in the polyptych; numerous shots of INGV researchers, at work at the Paternò salinelle, and of the monitors of the Catania monitoring room, which display the seismic signals recorded on Etna in real time.
The work HEART OF ETNA - sound sculpture 2017 mixed technique, iron, water and sound exciters instead it presents hours of infrasonic signals, i.e. sound waves recorded by microphones with a frequency below the audibility threshold, during episodes of lava fountains and explosive activity that have been transformed by a team of experts led by Marinos Koutsomichalis of the Norwegian University of Science and Technology, into frequency signals audible to the human ear. The infrasonic signal was then processed as a musical instrument, both visible, through the movement of the water placed in the sculpture, and tactile, through the perceptible vibration of the iron surfaces.
The harmonic tremor, protagonist of the installation, is therefore the sensory wave, the inaudible music that the active volcano produces. Its variations consist in the very strong and contradictory emotional impacts that it generates on the human being.
