Meaning

Three-part dramatic structure of introduction (jo), development (ha), and climax (kyū). A foundational compositional principle in Japanese classical arts.

Originally a musical tempo structure from gagaku court music — slow (jo), middle (ha), fast (kyū) — it was adopted into nō theatre by Zeami Motokiyo to describe the pacing of a play's movements. The concept was later generalised to describe the structural rhythm of any artistic or narrative work. It remains influential in Japanese aesthetics, dramaturgy, and compositional criticism.
