A floating floor, steel ropes, a humming piano wire and slender wooden structures that all insinuate themselves beyond the space make up this installation at CAT gallery, Hobart. Tertium Organum was part of Artist to Artist, a series of four short-run shows overseen by Kylie Johnson. This work was curated by Michaela Gleave.

Tertium Organum is the title of a 1912 book by P. D. Ouspensky which explores the fourth dimension. Tertium the installation was an attempt, not to represent the fourth dimension as such, but to take the viewer to the edge of the perception of a structure and a musical chord, where the space and silence beyond them can be sensed.
