Improvisation is an exploration of an unknown space. We navigate partly blindfolded along paths determined by unpredictable interaction between man and machine, and between people. Without a map, we have to probe and react, ponder and vary, explore and contemplate (what we have before we lose it). Trying to achieve the gestural freedom of acoustic instruments, I perform on custom electronic instruments together with Butoh dancer Nonoko Sato. The instruments are based on a novel mapping from physical gesture to sound, developed by Dahlstedt. In his research at University of Gothenburg. It allows a kind of physical phrasing that is difficult to attain with other electronic means, with a directness that mimcs that of acoustic instruments. Thanks to this kind of instruments, the musician can react to the most minute detail in the dancers movement, forming an intimate dialogue between musician and dancer.
