public square. A hall is a grand musical instrument. As always I worked with Xu Ya Ying, the acoustician. I love the contrast between the bright, snowy impression of the colonnade and the shade of the hall. Between these, the wall is a prismatic cliff, etched with strips of light where colour plays. The chamber music hall is set in a leaf that unfurls from the ground and rises against the colonnade; it plays with the filter, masking it diagonally, and this game of contrast between opaque and transparent endorses the unity of the project. I love creating architecture for music ... I feel that it expresses the dialogue between two realms of perception, hearing and sight, which respond to one another freely. There is a grace of space.

The emotion of music is the discovery and gradual entry into a different world, a world that reveals itself in time. I understand space too as a phenomenon that we perceive in the time of our movement, with its expectation, its surprises, its connections. Sound and light come to fill and reveal this marvellous void that opens between the solidity of constructed shapes, space and music reveal themselves reciprocally.
