In this video, it is heard how slowly, from the left side, in two octaves, the highest sound gradually moves to the right and becomes lower until the lowest note is reached, the same occurs from right to left, only in this case the sound becomes increasingly higher. In the middle, the sound altitudes and sound location are directly in the middle and coincide. The video is a visual reflection of the sound. This work is inspired by the work “Eqal Time” of Gary Hill. Recommended to listen on headphones.
