A mechanism within the piano is timed to go off every two to three minutes, thrusting the keys out of the keyboard in a cacophonous shudder. The keys, ordinarily the point of tactile contact with the instrument, fan disarmingly out into space. At the same time, the piano’s lid falls open to reveal the instrument’s harp-like interior, the strings reverberating at random. This unexpected, violent act is followed between one and two minutes later by a retraction as the lid closes and the keys slide back into place, tunelessly creaking as they go. Over time, the piano repeats the cycle. A mounting tension to the moment of release is followed by a slow retreat to stasis as the piano closes itself up like a snail withdrawing into its shell.
