VISITORS of the Egyptian Opera House expected Tuesday to be like every other day. But this turned out to be a mere illusion with Licia Galizia's musical studio. Galizia, an Italian artist, has brought to Egypt for the first time her Studio III su Volumi, an adaptive music and plastic art installation, which consists of Planephones in wood, Tecu copper, iron and aviation aluminum. The installation performs a process of transformation that makes it evolve musically in relation to what it registers from the surrounding environment, particularly when the structure is not used, or remains static for several hours. "This kind of art is new to Egypt and Italy as well," Galizia said. "This is also the first time for me to explore this kind of art with Michelangelo Lupone," she added. Michelangelo Lupone is the composer of this chart, but unfortunately he wasn't there to express himself and to explain how he and Galizia managed to come up with this idea. The materials of the installation are integrated by means of cuts and slits, which render the form dynamic and highlight its changeable nature. The position of all the mobile metal parts can be varied by the visitor, consequently giving rise to manifold musical and plastic and the musical form. It is very interesting though, because the new idea in this art included people's performance and opinions as well. Galizia's studio will continue to be held through February 8 at Egptian Modern Art Museum, the Cairo Opera House.
