On the contrary Xenakis considered that the rectangular constructions are less strong, natural and too “finished”, as distinct from S-curve structures which symbolize movement, infinity. By the time of the beginning of work on the project of pavilion Philips, I.Xenakis had already at original author’s hypothesis of music realization in space and in the form; what it a new musical formula of creative synthesis. By this time “Metastasis” what written by Xenakis-one of the most well-known orchestral works of the composer, with its notorious glissando of stringed instruments. There is the drawing of the Xenakis, where is pictured a plan of the movements melodic lines in this piece: their approaching, division, consolidation, exhaustion. Evidently, that the score of “Metastasis” look likethe scheme of a metal skeleton of buildings which were projected by Xenakis: Isolation by nature (controllable interaction).

Xenakis went further Corbusier and has suggested to refuse gardens at habitation designing, because this could help to protect the nature from irresponsible people invasion. The composer-architect believed that will be possible to supervise and stop mafic intrusions of people into the nature and planetary space, thanks to creation of the cities-buildings provoking the more compactness of people movements. Thus, the comfort of townsmen to be reached by possibility to breathe fresh air and to admire the nature through transparent walls, without interfering with its life. The flexible material. Light projections: Xenakis denies concrete completely, desiring as much as possible to use a space from the point of view of its economical and convenient layout, illumination, functionality. These are pellicles in space with a width of one hundred or one hundred and fifty meters, VPE and transparent, which would insure ventilation and visibility, light, etc. Designed in 1977 slide top of so represents a skeleton covered with a red elastic material. At creation of the monastery of la Tourette (1953-1960?.) Le Corbusier with help of Xenakis has embodied the idea formulated still 1922?.: “light and a shade show the form”5 having designed internal space of the main part of a monastery as a original black box.
