Iannis Xenakis used his diverse knowledge and understanding to challenge new ideas & approaches architecture & music,
among other things. This study aims to examine the works of Xenakis and to analyse working simultaneously in sound and
light and applying the same structures in another different fields. This study examines Philips pavilion, Polytopes and Diatope.
Results of this study are as follows. Philips pavilion :1.The pavilion's architecture with its hyperbolic-paraboloid shells makes
sound and light' space enrich. 2. Diversed sound and light' space make closed virtual space. Polytopes : 3. The steel cables acted
ad regulating lines of several large hyperbolic surfaces. 4. Musical space is diverse in verticality. And the light space is
composed of thousands of incandescent lights which mounted on a Cartesian grid. 5. Several layers of sound and light into
existing architecture make space superimpose. Diatope : 6. The Diatope is hyperbolic-paraboloid shells. 7. Musical space is
diverse in horizontality. And the light space is composed of thousands of incandescent lights which mounted on a Cartesian grid.
8. Philips pavilion ,Montreal Polytope and Cluny Polytope isolate and darken the interior space. The double-layered membrane of
Diatope is semi-transparent and its spatial effect can be controlled and has active systems. So the Diatope is open to the
enegetic waves that circulate in our environment.
