In a world of terrifyingly serious news, the opening of the Royal Ballet season with Frederick Ashton's pastoral frolic La Fille mal gardée might seem like a wanton disregard for reality, like a brass band playing "Oh I do like to be beside the seaside" as the Titanic goes down. But that is to misunderstand the reason Fille is so beloved is that it has at its heart a perfectly serious and realistic topic: young love.

Prospects hadn't seemed that great for this new Covent Garden Così. Could Semyon Bychkov, powerful earth-and-fire conductor of Richard Strauss's darker operas, possibly find the right proportions of air and water in Mozart? Would German director Jan Philipp Gloger prove better than his Bayreuth reputation? As it happened, the sextet of half-unknown principals never sang less than respectably, and the production had some good ideas, though mostly linked to the look of expensive sets rather than to focused work on the psychology of confused lovers.

Papa Haydn might have been tickled to see his early intermezzo, La Canterina, pack out the Wigmore Hall on a Monday night. A night for connoisseurs, then, but Classical Opera has form when it comes to refreshing classical repertoire with the elixir of vocal youth. And with a line-up boasting Susanna Hurrell, Rachel Kelly, Kitty Whately and Robert Murray, this was no exception.

A gorgeous white horse with flowing mane, poised and alert in a rocky landscape next to a watchful lion, is an extraordinary study of suppressed tension. A wistful North American moose, a herd animal living on its own on the Duke of Richmond’s estate; a monkey about to eat a crab apple – these are some of the subjects depicted by that artist of genius, the Liverpudlian George Stubbs (1724-1806).

Stanley Kubrick’s Barry Lyndon (1975), which has been re-released, is one of the most stately costume dramas films ever made. It is also a monument to tedium, a tale told so deliberately, ponderously, and humorlessly that it raises the question, as do Kubrick’s Paths of Glory, 2001: A Space Odyssey, Full Metal Jacket, and Eyes Wide Shut, of whether their maker was a genuine master or is a sacred cow. 

Happy returns of various kinds last night at the Wigmore Hall, where hall regulars the Brook Street Band (violins Rachel Harris and Farran Scott, cellist Tatty Theo and harpsichordist Carolyn Gibley) took to the stage along with a number of musical friends for a 20th birthday celebration concert. An all-Handel programme paid tribute to the composer whose London address gives the group its name, expanding outwards from the opening intimacy of trio sonatas and suites to finish with soprano and baritone cantata Apollo e Dafne.

Once confined to the concert hall, it’s a rare oratorio these days that doesn’t duck under the fence and sneak into the opera house. Bach’s Passions and most of Handel’s religious works have already made the transition, but this season it’s the turn of Haydn’s Creation. Rejecting the classic staged route, Garsington Opera have invited Mark Baldwin to choreograph it for his Rambert dancers. Add a trio of superb solo singers, Garsington’s own chorus and orchestra and artist Pablo Bronstein as designer, and you have an extraordinary hybrid conception.

To reach Sarastro's temple of wisdom, you have to climb a series of exquisitely manicured terraces to a tiny cloister in one of the world's great gardens. Iford Arts have been inviting high-quality small opera companies to perform and produce their own operas since 2005. Charles Court Opera, paragon of G&S and boutique panto, was the right team to ask to provide a Magic Flute tailored for a cast of nine and an audience of 80.

The huge and gorgeous Titian, The Vendramin Family, c.1540-c.1560, displays a frieze of males of all ages, three or four generations – and an adorable lap dog held close by the youngest boy – in marvellously sumptuous costume. The painting is surrounded with portraits by an ardent admirer of Titian's, Anthony van Dyck, our interest in the Titian deepened by the fact that Van Dyck once owned it. It is but one of the stars of this fascinating sampling of the collecting habits of artists themselves.

Natural disaster, in the shape of a metaphorical sea-monster ravaging classical Crete, might make a director's imagination work overtime on Mozart's first, jagged masterpiece. Alas, only unnatural disasters have been inflicted upon us in productions at Glyndebourne, ENO and the Royal Opera, with singers going some way to make amends. Now, at last, the green and pleasant valley of the Wormsley Estate has given birth to a clear and sober staging by Tim Albery that gives both the human beauties and the inhuman surrounding phenomena of the score their due.
