 Composing Sound Space in Interaction with the World 
This article explores the idea that while the usual approach to sound space in musical composition is generally practical, there is also the possibility of relating it to our inner space. Indeed, to conceive of and listen to the spatial arrangement of sound is, in a way, to externalize our interior space in the sound space of the world. After describing this and proposing the musical work and its hearing as a threshold between interior and exterior space, the text examines the relation established between the two. A new type of relationship is proposed, between the person who composes the musical space and the space itself. Rather than establishing a one-way relationship, where the world is only acted upon by us, the composition becomes a place where we may be transformed.
