Jo-Ha-Kyū

Ductus base_pattern · slow_accelerating_abrupt_end

A three-part structure: a slow, ceremonial beginning (Jo), gradual acceleration and intensification (Ha), a fast, concentrated climax and an abrupt ending (Kyū). The slow beginning has its own aesthetic value – it is not “less intense” but deliberately ceremonial.

Design question – How much room do you give the slow beginning? What happens in the stillness?

Reference example – Chess: a calm opening (jo), a dense middlegame (ha), time trouble in the endgame (kyū). Katamari Damacy: small things first, then ever larger ones, ever faster, until the countdown runs out.

Intensity

A slow ceremonial beginning, gradual acceleration, a concentrated finale with an abrupt end.

Compatible with

• Kishotenketsu (NA-03) – Culturally related (a Ludic Narrational Structure pattern vs. a Ductus pattern).
• Three-Act Structure (NA-01) – A similar basic movement without the ceremonial beginning.
• Hero’s Journey (NA-02) – A slow departure → acceleration → finale.
