There are two unifying powers in a cosmos of music: force field of tonality and structured time. Combination of these powers constitutes tonal chronotope. When explaining music with help of visual arts and mental images of science and philosophy, we extrapolate on temporal art of music such spatial categories as 'module', 'negative space', 'circular' and 'square', 'horizontal' and 'vertical', as well as notions of 'color', 'hidden dimension' and 'force field'. We can also present music in terms of geometry. The convenience that visual arts provide in explaining music points toward interconnectedness of the fine arts.
