Threnoscope is a spatialised microtonal drone instrument, developed by composer and live-coder Thor Magnusson, for use in improvised performances. Based on extended ideas of tuning systems, spectralism, scales, and drone music, alongside projections the instrument visualises shifting blocks of complex microtonal sound. Thor Magnusson and his Threnoscope will be joined in performance by Icelandic author Bergsveinn Birgisson, (whose performance practice investigates the citing and chanting of Old Norse text), as well as improvisers from Norway and Slovakia.
