In a room, there are several different chemical glass ampoules. The ampoules are filled with different liquid compounds and colors. Within each vessel, there is a waterproof speaker. The played audio is digitally processed and mixed with synthetic sounds, organized in a composition. The composition is realized by exploiting the different sound propagation relative to the liquid in each ampoule and according to the wavelength (frequency) of the color inside the ampoule. The perceived timbre effect is therefore dictated by the different “composition” of the fluids which have the function of sound filters. This installation is an alchemical composition, a dialogue between contemporary composition and physical principles.
