JD Walsh’s Triangular Motif uses the musical triangle a link between the visual formalism of minimalist sculpture and rule-based, minimalist musical compositions. As a sculptural video projection, it consists of images of percussive metal triangles, arranged into scrolling patterns, and struck occasionally by an off-screen performer. The performances are edited so that the triangular patterns also become a sort of granular musical composition - every few minutes clouds of sound are created by the many small tones. In this sense, the work also functions as a marker of time, in the way that a grandfather or cuckoo clock uses sound cues at preset intervals.
