[2007, commissioned by the singer Kornelia Bruggmann, who has performed it many times since]

Our composition resonatorium 1/07 (for soprano and space) is based on the very physics of singing in a physical space and uses a voice like a sonar, in order to fathom different resonance spaces and make their forms and characteristics clearly audible: the inner space of the singer's body (= inner resonance space) and the architectonic space of the performance location (= outer resonance space)
