Jo-ha-kyū (序破急): introduction, break, haste. In gagaku , the old court music, the word names the three movements of a piece. The Noh master Zeami applied it to the structure of a Noh play and to the order of plays in a day’s program.
The encyclopedia Mypedia notes that Zeami made a structure of five sections the basis of Noh composition: one section for jo , three for ha and one for kyū .
