All compositional relationships reduce to two principles: parallel (side-by-side reinforcement) and contrast (opposition)

Kandinsky identifies two master principles that govern all compositional relationships between elements: the principle of the parallel (setting side-by-side, where elements reinforce each other’s quality) and the principle of contrast (setting opposite, where elements oppose each other). This dichotomy applies across all element types: lines, planes, colors, and their combinations. In art, both principles are valid compositional strategies — parallel creates coherence and resonance; contrast creates tension, drama, and differentiation. For live visual coding mapped to audio, the same distinction applies: a visual element that is parallel to the music (same rhythm, same temperature, same energy direction) will feel unified; a contrasting element will create productive or disruptive interference.

Examples

Parallel: slow horizontal movement in a visual paired with a drone bass note (both cold, static, sustained). Contrast: slow horizontal movement paired with rapid high-pitched arpeggios (visual cold-static vs audio warm-dynamic). Both are valid — but the choice should be intentional, not accidental.

Assessment

In your current audio-visual setup, identify three element pairs (visual + audio). For each, decide: are they parallel (reinforcing) or contrasting (opposing)? Then deliberately flip one from parallel to contrast and observe the effect on the perceived relationship.
