Conlon Nancarrow (1912– 1997) is well known for his studies for Player Piano, as the intricate compositions would often exceed human performer limitations. He coded the music on paper rolls to be performed by the mechanic instrument. In this manner, he created complex, jazzy and hypnotic compositions based on algorithmic techniques and complex mathematical relations. These techniques influenced the melodic, rhythmic and tempo relations in the music. In the current project, some of these studies are orchestrated for Pipe Organ, Disklavier and electronics by Øyvind Brandtsegg. The work with the Nancarrow Studies also instigated further exploration of improvisation with these mechanic instruments in combination with improvisation software written by Brandtsegg.
