Let's imagine one note as a point on a plane, then an interval (2 notes) as a line connecting those notes. Next we have a chord (3 notes) and we get a triangle. By inverting the notes of the chord (135, 351 etc) we get a ring that representd different triangle shapes. Let's go into third dimension by adding one more note, thus a 4 chord can represent a pyramid.. you could also stay in 2D and represent a square etc.. by modulating and changing the tonal center you can move around the canvas or in space.. representing different data structures.. the horizontal movement would animate the structure as well!
