Dead Reckoning

“Dead reckoning” is a term used in shipping and aeronautical navigation. A continuous geolocation is being done by the help of different parameters such as direction of movement, speed and shipboard time. Those kinds of calculations are usually extremely prone to errors, since the measurements need to be constantly rectified with each change of course and acceleration. A fixed route is therefore only given by lining up successively determined course sections.This technical procedure served as a rough model for the present composition. This way I did for example take some longer computer simulated sections to which I applied several changes of direction. The original forms of this projection then serve as musical “standard situations”. Synchronous movements, cluster structures and tonal spectra are being precisely located, rectified and distorted, by the help of the possibilities of microtonal approaches. Next to these unpredictabilities, the course is also being crossed by a megaphone that briefly sends noisy signals from a double bass bow.
