There's now something of a gala atmosphere when the Orchestra of the Royal Opera House takes to the Covent Garden stage with its music director Antonio Pappano. Admittedly some of the players are not the same as when he took up his tenure, but the core relationship of 17 years - with the contract now extended to at least the end of the 2022/23 season - results in collegial music-making at an intense level which most orchestras can only dream about.

Mid Wales Opera makes small-scale touring look fun – even when you suspect that, behind the scenes, it really isn’t. Barely 24 hours before this performance of their current production of Ravel’s L’heure espagnole, and 11 dates into their current 16 date tour, their Torquemada, Peter van Hulle, was invalided out. Companies this size, and working on this budget, can’t carry understudies.

Here it comes - get a grip. The tears have started flowing in the trio "Quid sum miser" and 12 minutes later, as the tenor embarks on his "Ingemisco" solo, you have to stop the shakes turning into noisy sobbing. The composer then lets you off the hook for a bit, but only transcendent beauty in singing and playing can achieve quite this effect in Verdi's Requiem.

Not all composers require the finger of mortality pointing at them to develop what becomes a late style. Charges of detachment and even indifference have been levelled at the B flat major Piano Concerto K595 which Mozart completed early in the year of his death, but Mitsuko Uchida’s playing of it on Saturday night was as refined, as weightless and translucent as her trademark silk tops.

How do you make your mark in a crucial last week after the Olympian spectaculars of Kirill Petrenko's Proms with the Berlin Philharmonic?

“What drivel! What nonsense! What escapist Techicolor twaddle!” No, not a description of Wallis Giunta’s scintillating BBC Proms at Cadogan Hall recital, it’s a lyric from “What A Movie”, Leonard Bernstein’s outstanding stand-alone number from his one-act opera Trouble In Tahiti. Narrating the story of a ridiculously torrid movie the heroine has sat through, Giunta joyously inhabited its every moment and delivered it with complete theatrical assurance.

“It has a music of its own. It produces vibrations.” Oscar Wilde was being ironic when he had Gwendolen contemplate the sound of her beloved’s drab name in The Importance of Being Earnest, but he had a point when it comes to composers and poetry. With their own “vibrations”, great poems rarely warrant musical interference; bad poetry, meanwhile, can resist even the finest scoring.

You can always be sure of impeccable casting and spirited playing as Ian Page takes his Classical Opera through Mozart year by year. Just don't expect more than the glimmer of genius to come in 1768, though. It doesn't matter in those admirable showcase programmes highlighting the young Amadeus alongside more mature voices of the year in question.

Singing satirist Anna Russell placed the French chanson in her category of songs for singers "with no voice but tremendous artistry". Mezzo Karen Cargill has tremendous artistry but also a very great voice indeed, a mysterious gift which makes her one in a thousand, and also rather good French (put that down to Scotland's "Auld Alliance, perhaps).
