In the mid-nineteenth century, Scottish mathematician Hugh Blackburn invented the harmonograph, a device that draws elegant abstractions through the movements of two or more pendulums. Blackburn observed that the visual “harmonies” resulting from intervals of ratio in pendulum height correlated to similar steps in the musical scale. University of Chicago musicologist Larry Zbikowski is exploring the visual patterns of movement made by dancers of the waltz, and correlating these patterns both to the musical scores that accompanied the dancing and to states of emotion and consciousness in the brain. These synchronistic models serve as inspiration for Conrad Freiburg, whose virtual universe, erected in the main gallery at the Hyde Park Art Center, is divided into sections matching the seven notes of the Western major scale with sconce-like chimes affixed to the wall. While Freiburg doesn’t claim adherence to any esoteric system, the number seven recurs throughout occult cosmology; in theosophy, for example, the seven-step “septenary” describes the various “energy envelopes” of the soul that exist in subatomic emptiness.
