Does “the practice of opera singing in Italy” need help from UNESCO, which has newly inscribed it on the “Representative List of the Intangible Cultural Heritage of Humanity”? Italian opera is surely immensely popular worldwide. But when it comes to practising the art properly, its greatest senior exponent, Riccardo Muti, powerfully argues that Verdi and Bellini, his most recent special projects in the city where he lives, Ravenna, need as much respect and care as Beethoven or Schubert.

Having previously brought us adaptations of M R James’s ghost stories, reviving the BBC tradition inaugurated by Lawrence Gordon Clark in the 1970s, Mark Gatiss has now turned to a short story by Arthur Conan Doyle for his annual Christmas chiller. With its cast of upper-crust academics amid the shadowy staircases and wood-panelled studies of Old College, Oxford in the 1880s, it makes a fine addition to the canon.

Sir Mark Elder’s zest for exploring fresh territory with the forces of the Hallé is unquenched even in his final season as music director. And who better to introduce the Stabat Mater of Rossini – a late flowering of the operatic wizard’s powers – than he, a champion of the rich and rare from operas past?

Sir Ridley Scott has taken umbrage at the French critics who weren’t too impressed with his new movie. Not only do they not like his film, but the French “don’t even like themselves”, according to the dyspeptic auteur.

Last night saw two pieces of late 19^th century French choral music – one a hugely popular staple of choral societies around the world, the other a complete novelty, lost for a hundred years – brought together in fascinating juxtaposition by the French period-instrument orchestra Insula, under their founding conductor Laurence Equilbey.

The Fauré Requiem and Gounod’s Saint Francois d’Assise shared a radiant contemplation of death in music that is at once highly refined and yet utterly direct. They were both, in their different ways, exquisite.

A flea bites a rat which spooks a horse which kicks a man and… an empire falls?

It is 1864 and the lush green lawns of Knowl, the stately home in Ireland that Maud Ruthyn (Agnes O’Casey) will inherit when she reaches the age of 21, are beautifully kept. Everything is in its place. Maud expects deference, especially from the domestic staff.

Parliament may be topsy-turvy, with a motley bunch of Lords the only hope in vetoing outrageous bills, but up the road at the London Coliseum a more disciplined company is steering a luxury liner with perfect craft. Cal McCrystal’s best G&S so far, where fairies meet peers with, as the cliché has it, hilarious results, was a winner first time round, with gorgeous designs by Paul Brown taking fairyland, Arcadia and Westminster seriously. 

Ben Gernon’s relationship with the BBC Philharmonic has been a richly rewarding one over the close-on seven years since his appointment as their principal guest conductor began, and indeed subsequently. 

The impression gained on his first Bridgewater Hall concert with them back in 2017 – that one of his instincts is to give an orchestra what it needs and then let the players do what they do best – was again clear in this programme of popular repertoire works which he took over from an indisposed Mark Wigglesworth.
