In addition to an extensive installation for the church space, artist Susan Philipsz developed a separate sound work entitled Broken Ensemble for the Collegekamer of Oude Kerk. The work consisted of a sculpture of three organ pipes that each channelled the sound of the artist’s breathing through a loudspeaker placed in each pipe. Thus, the sound recording seemed to play the organ pipes and the breathing brought the instrument to life. The physical effort of producing sound was clearly audible and the resonating rhythmic tones were reminiscent of sleep. The combined effect of sleep as a metaphor for death and breath as a symbol for life alluded to mortality. Breathing has played an important role in the works of Philipsz who is frequently described as a sound architect.
