the way of searching for sound "harmony" is reminiscent of the way of searching for a group, to which the person will join or break away. thus, the visitor, through the flow and duration of sound, can redefine, heterodetermine, adapt and shape a kind of personal  comprehension of he sound identity. the sound is produced by touching, or rubbing, a stethoscope against the concrete block, the basic building material of the modern world.  a modern musical instrument allowing each user to experiment, a visual work that comments on socialization as a process in which we constantly receive new stimuli and experiences, or both. a slab of concrete, a stethoscope internally connected to a piezo contact microphone, various sound effect pedals and a speaker.
