Tatsachen in zwei Sätzen is the first piece equipped with an opus number. Nearly all prior scores have fallen prey to destruction or have been lost. Exempt from this are some of the prior electroacoustic music and sound installations. The initial idea of the work was to transform the violin into a strongly polyphonic instrument. In order to do so, the two hands of the players perform separate actions over long stretches. The Tatsachen are a virtuoso solo piece, strongly inspired by Lachenmann’s musique concrète instrumentale. For example, part A-2 evokes clear references to Toccatina, but its main element – dabbing the strings with the screw of the bow – is taken to an even more advanced level. The piece was revised once the development of a notation system for unconventional extended playing techniques (Dimpker: Extended notation. Vienna 2013) had been finished. The revision was extensive, but mainly concerned with the methods of notation, not the content of the piece.
What is necessary to perform this work?
The violin is amplified. Therefore, two condenser microphones with cardioid polar pattern in XY-configuration (at an included angle of 90°) are utilised (ossia: via contact microphones or supported by these). The microphones send to stereo loudspeakers. The setup is determined by the sound engineers. The loudspeakers’ output level is generally supposed to be equal to the dynamic level of the sound production.
