A clear base pulse must be established before it is broken — an unbroken pulse is static and an unbroken lack of pulse is formless
Compelling visual rhythm depends on first establishing a legible base pulse and then breaking it deliberately, rather than doing only one of the two. An unbroken, never-varied pulse is hypnotic but static; a total absence of pulse (continuous unstructured change) reads as soup with nothing for the eye to hold. The move is to set a steady beat the viewer can lock onto, then introduce accents and variations against it — the visual counterpart to establishing a groove before syncopating it. Both extremes fail: pure repetition and pure formlessness.
Examples
Run a steady visual-pulse for several bars so the eye locks the tempo, then drop or double the pulse for one bar as an accent before returning. Contrast: an ever-changing warp with no steady reference, which never establishes a beat to break.
Assessment
Explain why both an unbroken pulse and an unbroken lack of pulse fail as visual rhythm, and describe the two-step move that avoids both extremes.
