Tension is built by ramping one or two dimensions over a phrase then resolving on a boundary
Tension in a set is a ramp followed by a resolution: raise one or two dimensions of energy (density, brightness, motion, space, register) gradually over a phrase — the build — then resolve them on a section boundary — the drop or release. Ramping only one or two dimensions leaves the others as headroom for later; raising everything at once has nowhere left to climax, because a resolution reads as release only relative to a tension that was still incomplete. The structure is therefore deliberately partial on the way up so the boundary can deliver the payoff.
Examples
Over a build, ramp density and brightness while leaving space and register untouched; resolve on the boundary with a drop. Maxing density, brightness, motion, space, and register together in the build leaves no dimension free to make the boundary feel like an arrival.
Assessment
Explain why ‘raising everything at once has nowhere to climax.’ Describe the ramp-then-resolution shape and why the ramp should move only one or two tension dimensions.
