Transformation (2009-2011) (completed)

Transformation is an improvisation piece for electric violin and live electronics. It is based on the idea of letting the performer control a large collection of sound fragments while moving around on stage. 


The technical setup for the piece is based on a video-based motion tracking system developed in Jamoma, coupled to the playback of sounds using concatenative synthesis in CataRT


The piece has been performed, in different versions, at the following locations: 

  • Norwegian Opera & Ballet on 26 November 2009
  • National library of Norway on 4 February 2010
  • Norwegian Academy of Music on 3 September 2010
  • Norwegian Academy of Music on 28 March 2011
