Right: E-mail from Øyvind Torvund to Ingfrid Breie Nyhus with one of the tasks towards Det abstrakte i folkekunsten, stating: 'I have an idea for a new etude, only described by words. -Piano reduction-: Take one of Grieg's dances, or a short excerpt. Change the original pitches, or reduce the note material to only a fifth in several octaves. Listen to the original dance, focus on rhtyhm, timing and dynamics. I am looking for a result that sounds like a rhythmical analysis, a rhythmical essence of the slått, a true piano reduction.'
