The school opera goes back to the Japanese fable Tanikô, a play from the Nôh theatre. Weill composed Der Jasager in the first half of 1930, pausing only for the turbulent première of Aufstieg und Fall der Stadt Mahagonny on 9 March 1930. The term “school opera” gave Weill a number of possibilities for combining the concepts of “education” and “opera”: the opera teaches the composer – or a whole new generation of composers – to approach the operatic genre in a new way. But it is also a question of re-training the process of operatic performance, with the end goal of staging the work so naturally and simply that children become the ideal performers. And finally, Weill also considered “school operas” as meant for use in schools: “it is thus essential that a piece for schools should give children the opportunity to learn something, beyond the joy of making music.”
