Perhaps the only film whose content is totally based on the musical form known as canon. The first sequence is a simple demonstration of the canon "Frere Jacques" where four cubes dance and combine with one another on a checkerboard. The second sequence show four little human-like figures dancing in space. The third and most elaborate sequence shows a human going through several strange gesticulations. Through multiple printing we realize that the man, as in the previous sequences, is part of a visual canon and is making the gestures to himself. As we hear variations on the canonic theme so too do we witness visual variations: a woman and cat enters the canon. To show the musical technique of inversion, the image of the man is printed upside down.
