It's awfully long for a fairytale in which a mystery prince helps a damsel in distress, and she asks him the question she shouldn't. Myth tends to go deeper, as Wagner did in The Ring of the Nibelung after Lohengrin. Here he captures the magic of transformation and transcendence, but in between there's too much hard-to-stage pomp.

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.

Brilliant and innovative though it is in many respects, The Flying Dutchman is by no means a straightforward piece to stage. It’s an odd, sometimes uncomfortable mixture of the genre and the epic. At Sadler’s Wells in the sixties they had a little ship and a big ship that hove into view, a fishing village, sailors with tankards and striped shirts, and girls at looms.

Like the comedies of Mozart – the genius the artistic milieu depicted in Capriccio seems to be waiting for, if its original 1770s setting is observed – the more conversational operas of Richard Strauss depend far more than one often realises on conducting that sets a stylish, buoyant pace. Without it, and even more more rehearsal time than Garsington allows, musical heaven remains just out of reach.

A proper production of Così fan tutte should make you feel as if the script for a barrel-scraping Carry On film has been hi-jacked by Shakespeare and Chekhov – working as a team. The story is so silly (even nasty), the music so sublime.

Something is afoot at Garsington this season. Walking past the lake you might just catch sight of three strange figures in the distance – white-clad pawns engaged in a solemn game of human chess. Continue towards the auditorium and, somewhere among the topiary, there’s a splash of colour. A man with the cap and long red robes of an Inquisitor stands silently and contemplates the statuary. Opera, once again it seems, has fallen through the looking glass.

If Hugo von Hofmannsthal's libretto for Richard Strauss in their joint "comedy for music" is the apogee of elaborately referenced dialogue and stage directions in opera, Richard Jones's realisation - for all that it throws out much of the original rulebook - may well be the most rigorously detailed production on the operatic stage today.

Puccini’s heroines and the rough treatment he hands out to them have come in for plenty of opprobrium over the years.

Let's face it, Robert "Cabinet of Dr Caligari" Wiene's 1926 film loosely based on Strauss and Hofmannsthal's 1911 "comedy for music" is a mostly inartistic ramble. Historically, though, it proves fascinating.

A rope is mercy; a razor-blade to the throat, a kiss; a red-hot poker… But, of course, we never get anything so literal as the poker in George Benjamin and Martin Crimp’s elegant, insinuating retelling of Christopher Marlowe’s Edward II.
