At the end of the 1970s, during his exile in São Paulo, Ferrari started to work on the Esculturas Sonoras (Sound Sculptures). Based on the Brazilian berimbau instrument, he constructed these sound sculptures with vertically aligned metal sticks which he fixed in part to the lower end (Cajon), in part to the upper end (Medusa) and in part to both ends. They court direct interaction with the beholder. Ferrari, who in numerous performances himself experimented with his sound sculptures, describes them as an invitation to experience music in a playful manner: "Let them play who want to, not just them who 'know how to'."
The sound sculptures Medusa, which the Fundación Augusto y León Ferrari – Arte y Acervo discovered on old photographs and had rebuilt, and Cajon link the visual, acoustic and tactile experience in Ferrari's work. Thus they represent his definition of art as experience.
