Trapping Canon is a video which illustrates the repeated and restricted life in the time of pandemic, accompanying selected audio clips from Canon BWV 1087 written by Johann Sebastian Bach. In the time of pandemic, people are accustomed and subjected to the reality that we are trapped in daily routine, spatially and timely. We are limited, and we are segregated. Following the principles of social distance, everyone stays in individual space, forming a collective grid of facade, for the buildings and for the world. Supermarkets are the few spaces where we run for a larger volume of freedom. Nevertheless, the repeated stacks are just another configuration of repeated maze. The classic music strategy of Canon is to repeat the main melody, and adjustments for each chorus are added to accomplish a harmonic symphony. In Trapping Canon, the actor goes through the alleys in the supermarket, where the world is reverted, flipped and overlapped according to the rhythm of the Canon. The actor is trapped in the dream-like world, while she enjoys the healing music. When the world zooms out, the supermarket disappears and the grid appears as the main visual character. Tomorrow is another day walking through the Trapping Canon. It is a collaborative work with Jiajian Min, featured in Ars Electronica .ART Gallery 2020.
