Itaipu is a four-movement symphonic cantata by Philip Glass. The composition was written in 1989, and pays homage to the world's largest hydroelectric dam, built on the Paraná River between Paraguay and Brazil. The text is written in Guaraní, with a translation by Daniela Thomas. It was commissioned by the Atlanta Symphony Orchestra and Chorus and was first performed on November 2, 1989.
The four movements are titled:
- Mato Grosso
- The Lake
- The Dam
- To the Sea
The hydroelectric project that this work celebrates was in fact embroiled in much environmental controversy because it was constructed without public consultation, and its construction inundated Guaíra, an immense series of eighteen waterfalls upriver and one of the largest and most spectacular in the world. It is not known whether Glass was aware of this environmental damage when he accepted the commission, traveled to Brazil, and visited the project.
