The composition is divided into four parts. The first movement A and the last movement D work equally with all the groups of the orchestra. In these movements the material
moves through the frontal and panoramic acoustic space, on
on the other hand, the middle two parts are focused primarily on
dominance of the right and left instrumental ensemble groups. These movements draw on material from a different time period from the
the original recording and also differentiates itself into harmonic and rhythmic
levels. This differentiation into four parts is also carried through
the rasterization setting of the analysis, resulting in a gradual -
descending harmonic tension release.
