First, confessions. I’m the dance critic here at theartsdesk. Yes, this is a review of a concert performance of an opera, and no, I haven’t picked up a detailed knowledge of Rossini’s oeuvre as a byproduct of my education in pirouettes and Pina Bausch. I attended last night’s concert as a common or garden punter, and a chance one at that, taking a ticket to save wasting it after its original owner had to give it up because of a work commitment.

“Ah now, I can’t promise you sun,” says a Scots lady-in-waiting of her native weather to a novice Englishwoman near the start of Rona Munro’s masterly James Plays. It’s the first of many references to make the audience laugh knowingly. Well, after four days of the worst weather Edinburgh Festivalgoers can remember, the sun came out yesterday morning. There’s no better place to be than the airy Queen’s Hall if you want an 11am recital of light and shade – and to say that of yesterday’s duo programme is an understatement.

On paper this was an interesting programme. The Edinburgh Festival traditionally opens with a major choral work, but while the international audience would probably be happy with endlessly recycled requiems and masses, festival directors have often felt obliged to venture into more challenging territory. So for last night’s opening concert the chorus had prominent roles in two separate works on either side of the interval: Scriabin’s Prometheus, The Poem of Fire, and Debussy’s Le Martyre de Saint Sébastien.

Despairing in the depths of the Second World War, Richard Strauss turned to Mozart’s string quintets as well as the complete works of Goethe for evidence that German culture still existed. Vaughan Williams might well have done the same for his native art during the so-called Great War in homaging the music of Thomas Tallis.

The sprightly tread of Handel’s Queen of Sheba, attended by two wonderful Turkish oboists, wove the most fragile of gold threads between full orchestral exotica and Rameau motets of infinite variety last night. Not that any more links need be found: it’s the addition of the late night events which turns the Proms into a real festival, not the mere concatenation of concerts you might find in the main orchestral season.

José Mourinho is Setúbal’s most famous son. Non-Portuguese readers are not expected to know the two other celebrities most feted by this extraordinary port city on the estuary of the River Sado, with miles of sandy beaches opposite where a school of dolphins resides and the lush national park of the Arrábida mountain range just to the west.

On the back wall of Birmingham Symphony Hall’s great oval space, two musicians are poised on a glass balcony that gives the illusion of not being there at all. A small square of warm light picks them out, vivid against the hall’s darkness. So framed, Saint-Saëns’ gentle Prière for cello and organ keeps its intimacy even in that large space, the two instruments blending into one equal sound that is clear, golden, and not too sweet.

The last time the BBC dramatised the creation of a great musical work, it didn’t quite hit the spot. Eroica starred Ian Hart as Beethoven glowering at the heart of a drama which had rather less of a narrative through-line than the symphony it honoured. For Messiah at the Foundling Hospital, the BBC have gone to the other extreme and kept eggs out of the one basket. There was a bit of drama, a bit of documentary, some costumed musical performance and there were even two presenters to come at the story from opposite angles.

This was the first of three Royal Festival Hall concerts during the first half of 2014 from the Royal Philharmonic Orchestra and its principal conductor Charles Dutoit, all three programmes consisting entirely of French music. The other two will be in May. In between the Swiss-born conductor, a sprightly 77-year-old, will have picked up a Lifetime Achievement gong at the International Classical Music Awards in Warsaw.

“A little skill, a little heart, that’s all,” wrote the 70-year-old Rossini as epigraph to his late, not so small and not always solemn mass. It’s not all, of course. This last major self-styled “sin of old age” (péché de vieillesse) stands in a similar relation to his final, epic opera Guillaume Tell as Verdi’s Falstaff does to his Don Carlos. Only in Rossini’s case the gap was longer, nearly 35 years, and no Otello intervened (Rossini had composed his own operatic version of Shakespeare’s play back in 1816).
