“One of my first 16mm films, made without a camera as an experiment in how to visualize rhythm. It equates four simple shapes with four simple sounds, made by punching shapes into black film and scratching into the film’s optical sound track. The film uses a bar structure similar to a music score. Each bar lasts one second (24 frames of film) and is divided into 2, 3, 4 or 6 aural and visual beats per second. These are used in alternating patterns such as: 2/3, 3/4, 3/4/6, 2/3/6. In each section of the film an arbitrary relationship is established between image, sound and beats per second.” (Guy Sherwin)
