This became far too virtuosic to be sung. We ended up with a heterophony of 3 parts, the same line with three levels of ornamentation. The singer used a version of the original plainchant, within the same quarter tone mode, with vocal ornamentations like trill, trillo (amplitude vibrato), and slow oscillations. Jostein performed slower diminutions on the recorder. The rapid, unplayable diminutions were assigned to a sampled harpsichord spatialized to different parts of the room. A sampled ensemble of crotales, slentem and gong ageng marked the beats.
