There was always in the mind of Xenakis the idea of utopia and the imagination of the ancient cosmogony. In effort to achieve this utopia, he designed and built multimedia applications where place plays a major role, the Polytopes.

Diatope, which was designed for the inauguration of the Centre of Georges Pompidou in Paris, was characterised by a detachable architectonical composition, which expanded the paraboloid excesses of the Philips Pavilion. It housed an audiovisual installation, which reproduced the electronic music project “La Légende d’Eer”.

The electronic music track ,written by Xenakis for Diatope, has not a specific subject. It uses however the first excerpt from the end of state of Plato, which refers to a soldier whose name is Eer, who returns from the dead and describes what he saw on the other side. The vision will culminate with the observation of the “Spindle of Necessity”, a major axis surrounded by eight rings representing the eight celestial spheres -known in ancient astronomy-. In each ring stood a siren who chanted sounds corresponding to the axis of the region and together formed a cosmic harmony.

Xenakis in Diatope tried to match space together with a spectacular laser installation, with the electronic music track “La Légende d’Eer”. This 45-minute audio became a starting point for this thesis for readjusting its relationship with space, from introvert to extrovert , for a different scale and based on an effort of semantic mapping.

The patterns are representing acoustic parts and subsets characterised by specific motifs (depending on the dynamics , frequencies, rhythm) . These patterns formed the design vocabulary.
