Earth–Moon–Earth (Moonlight Sonata Reflected from the Surface of the Moon) by Katie Paterson
Earth-Moon-Earth (E.M.E) is a form of radio transmission whereby messages are sent in Morse code from earth, reflected from the surface of the moon, and then received back on earth. The moon reflects only part of the information back – some is absorbed in its shadows, ‘lost’ in its craters.
For this work Beethoven’s Moonlight Sonata was translated into morse code and sent to the moon via E.M.E. Returning to earth fragmented by the moon’s surface, it has been re-translated into a new score, the gaps and absences becoming intervals and rests. In the exhibition space the new ‘moon–altered’ score plays on a self-playing grand piano.
