Diagnostica 4 was built in the Museo de Bellas Artes "Castagnino" in Rosario City,
Argentine, during the 3rd biennal of the critic in 2000.
Several test tubes full with water were settled. Each of them let the dripping over a hot plate that
evaporates the drops that fall on them inmediately.
The drops are made up very slowly in each test tube so they produce a tension int the waiting time. After
their falling they become ephemeral and ambiguous as vapor and they vanish in the air. Since each driping
is aleatory it is not known which drop will fall first and what place and how long will last for the intervals
of silences that happen between each sound of evaporation of dripping over hot plates is reavalued.
It is a sound installation that make worth of attention each of the noisless periods. When the rhythm of dropping
is faster in each test tube the sounds of evaporation satrt to relate among each other, giving the way to searching
of an order on sonority, inside the aleatory of all evaporations.
