Canon per Tonos is a modulating canon which means that the tune changes key. Bach has contrived to modulate (change keys) right under the listener’s nose.
The canon shows the strange loop phenomena: by moving only upwards or downwards through a hierarchical musical system, one finds oneself back to where one started. This method remind us a divine power to control time and space in other terms the sense of eternity expressed by music. Beating rhythmically, no one is first, no one last, all are the same all beat in the same way. The rhythm takes over, a sense of infinity arises from this human ring that turns and beats rhythmically.
Dance could be a way to articulate an eternal present and illusory balance.
