Chiari is the main Italian exponent of the Fluxus group and one of the greatest Italian artists of the twentieth century. With a clear reference to the work of John Cage, he starts from musical research to arrive at the ritual and symbolic destruction, but partly also material, of the piano, the musical instrument par excellence, the emblem of all sonic conformity. His scores, oriented on musical theoretical principles, consist of accurate instructions (not musical notes) which in general can be performed by anyone. Each object can be used as a musical instrument, the only decision is the will to make music and to act. The artist is of little interest if and in what way the music is received, the more important is the action that each one carries out on his own initiative. The FLUXUS work was created specifically for the MU.SP.A.C. during the meeting "The street and music" held in 1997 in the first location of the museum. The artist performed numerous performances for the occasion such as Gestures on the piano, an action that consists of composing sounds by touching the keys of the piano not only with the fingers, but also through the arms, elbows and wrists. In this way the whole body comes into contact with the musical instrument and the sound result is enriched with new meanings: the piano becomes the equivalent of the canvas.
