Music Stands (2011) for two music stands, two small loudspeakers, contact microphones and live electronics.
written for the Backofen Festival by Maru Rieben
Two music stands are unfolded at the start of the performance. Both are amplified using a contact microphone glued onto the stand and a small loudspeaker, placed on the floor. During the performance, the loudspeakers are placed on the stands. The vibrations of the loudspeakers are transmitted through the metal of the stands back to the contact microphones and in this way a feedback loop occurs (similar to that in Nodalings by Nicolas Collins, as described in chapter 4). By changing the altitude of the stands, the distance between microphone and loudspeaker changes, and therefore, the feedback sound changes as well. Unfortunately, I do not have any documentation of this piece, but the beginning of Stumme Diener is very similar to it.
