The motivation for this text is my ongoing research into creating a uniform and comprehensive notation system for music regardless of sound sources, acoustic or electronic. I propose a way to visually represent the positions and movements of sound in composition and analysis of music which in different ways utilises space as a parameter. I address a number of aspects of spatialised music to take into account when defining a notation language for the music. I suggest visually representing the room in different ways depending on how the music relates to the concept of space: as projections from the center of a sphere for more structural work, or as coordinates in a cubic room for works that depict a physical or imagined space. I also show how these descriptions of space are integrated with my existing notation system.
