Planetariums have been home to spatial visual music for over sixty years. Advanced technology in spatial sound such as sound field and wave field systems are superseding channel-based systems as areas for research. Nevertheless, there is room for invention in immersive spatial visual music in a channel-based planetarium. Circular seating minimizes problems with sonic reflections from circular walls suffered by unidirectional theatre seating arrangements. Circular seating supports dynamic permutation of channel-to-speaker routing as a corrective and compositional measure. Full dome projection of visuals gives inherent support for graphics-to-music spatial correlation and related immersive effects. This paper is a case study of the aural architecture of one small circular planetarium and the visual music composition and performance approaches that it supports.
