Piano+ 2009 – Gero Koenig: Chordeograph 2

The vision to create extended listening experiences led Gero Koenig to sound modulations that go beyond the boundaries of static tonal systems. From his sound research, the artist invents and constructs new instruments. 

The flow of sounds is controlled by moving a „slider“ made of metal, wood and glass on the strings of the instrument Chordeograph 2. The different positions and gestures possible with the sliders (including direction, angle and speed of movement) offer a soundspectrum that transcends previously known string instruments. Each movement is reflected in sounds ranging from minimal to dramatic. 

On the basis of graphic scores Koenig develops precise and repeatable playing procedures. Line-laser modules serve for Chordeograph 2 to project score information onto the strings of the instrument. Due to the time- and pulse-bound control of the guiding laser beams, the information of the score is fully integrated into the instrument.
