A Broadway show as melodically haunting and sophisticated as it is niche, The Light in the Piazza has taken its own bittersweet time getting to London. A separate European premiere in 2009 at Leicester's Curve Theatre whetted the local appetite for a show that won six Tony Awards in 2005 but is far from standard musical fare.

"I am amazed to be still alive. Two hours of medieval torment.” Franco Zeffirelli - who has died at the age of 96 - had spent the day having a lumbar injection to treat a sciatic nerve. You could hear the bafflement in his heavily accented English.

All happy 18th century couples are alike, it seems, and that makes for a certain placidity in Gluck's pastoral Bauci e Filomene for the (unhappy) wedding of Ferdinand, Duke of Parma and Maria Amalia, Archduchess of Austria. All unhappy couples are unhappy in different ways, especially if the marital misunderstanding takes place when you're bringing your wife back from the land of the dead.

There’s a barely disguised sense of threat running through the 2019 Venice Biennale. Of the 79 participating artists and groups, all are living and there’s a sharp sense that the purpose of the exhibition is to diagnose the ills afflicting the contemporary world.

Leonardo da Vinci died 500 years ago on 2 May this year. We all know he was a painter, sculptor, architect, engineer, pioneer of flight and anatomist – yet according to Vasari, Leonardo’s first job outside Florence was as a result of his musical talents.

Paper is traditionally the medium though which artists think. Stray thoughts and experiments can be quickly tried out, pushed further or jettisoned. There are no penalties for starting something which goes wrong or transforms into something else because material is cheap, expendable. Erasure or high finish are equally likely, dead ends and new directions begin in the same place.

"Them" - the "loro" of the title (with a further play on “l’oro”, gold) - denotes the mostly sleazy opportunists willing to use and be used by "him" ("lui"), "Presidente" Silvio Berlusconi in his septuagenarian bid for an extended sexual and political life.

Italy has a romance with rural grit and innocence and – perhaps not surprising in a country where the links between village and city are still very strong: Alice Rohrwacher’s Happy as Lazzaro (Lazzaro Felice) isn’t in any way derivative, but revisits some of the same territory as Olmi’s The Tree of Wooden Clogs (1978) and the Taviani Brothers’ Padre Padrone (1977) and Kaos (1984), all classics of the genre.

When in 1800 the architect Sir John Soane bought Pitzhanger Manor for £4,500, he did so under the spell of optimism, energy and hope. The son of a bricklayer, Soane had – through a combination of talent, hard work and luck – risen through the ranks of English society to become one of the preeminent architects of his generation.

Would Verdi and Puccini have composed more non-operatic music, had they thrived in a musical culture different to Italy's? Hard to say. What we do know is that they both became absolute masters of orchestration – Puccini rather quicker than Verdi, living as he did in an entirely post-Wagnerian era.
