So La Scala is reopening. Many will talk about the restored building and the state of its acoustics. But there is one topic they don’t bring up: “There is no getting away from the fact that, like every other aspect of the Italian operatic pyramid which it commands, La Scala is in decline. No Italian opera of importance has been written since the death of Puccini 80 years ago. There is no obvious successor to Muti. And the standards of Italian singing are declining by the year.”
