Door–cord–pulley–bottle–piano is an intervention in public space in which the artists have connected a cord going from the door handle of the gallery's entrance (located in the ground-floor) to a piano in the first floor, both floors being separate spaces without connection. Each time a visitor opens the gallery door, a bottle of water gently falls over the keyboard and plays a chord on the piano in the first floor. The gesture of opening a door causes an action of a very dissimilar nature. However, this action cannot be perceived by gallery visitors; Just the ones who are working in the office on the first floor can hear the sound of the piano.
