In the video, Barcelona's landscapes are adapted as an environment to create a unique score of a work performed at the same time by a set of virtual instruments. Insufficient standard music notation is replaced by an unconventional visual code with a performative character. The video is based on the pitch phenomena, a perceptual property that allows the ordering of sounds on a frequency-related scale. The composition is made of four frames, in which the moving figure determines the pitch on the scale of each frame, from higher to lower. The video was created by Jacek Doroszenko as part of the Artist-in-Residence programme at Fundació AAVC Hangar in Barcelona, Spain in 2014. Ewa Doroszenko was featured as a performer.
