During the initial explorations with the camera, however, the observed pattern changes remained a fond memory until 2021. Then I found a computer specialist, who agreed to create a computer program, that would allow me to build a quatroscopic matrix based on the input of a single square image, and then move parts or all of that image to the rhythm of a musical tune. In this program I can first mount a music piece along a time axis. On a second track I can add a square image, which can be moved along the same time axis by marking new positions at points of changes in the melody of the music piece. The program then produces all the images between the markers at 60 frames per second and stores then in a folder. In a follwing step, these images are assembled into a short film. I call these short films Audioquatroscopies.
