Striking it lucky with a successful new opera is a rare occurrence, though every company has a duty to keep on trying. The Royal Opera hit the jackpot with 4.48 Psychosis, a highly original approach to Sarah Kane's profound and authentic play by Philip Venables, the first Doctoral Composer-in-Residence on the scheme initiated by Covent Garden in alliance with the Guildhall School of Music and Drama. How could one not wish his successor, Israel-born Na'ama Zisser, all the best?

If you go to ENO’s Acis and Galatea expecting a grassy knoll draped decoratively with a Watteau shepherdess or two then you may be disappointed. Launched in 2017, the company’s reliably punchy Studio Live strand (stripped-back, small-scale, off-site performances) continues here with Handel’s “little opera”, reinvented for the Instagram age. #Nymphsandshepherds #Flockthis

Juanjo Mena, chief conductor of Manchester's BBC Philharmonic for the past seven years, took his official leave of them with a programme reflecting his great love, the music of his Spanish homeland. Albéniz and Falla, to be precise, and the greater part was a complete concert performance of the latter’s opera La Vida Breve.

What a great show, on every level. David McVicar’s Glyndebourne production of Handel’s Giulio Cesare, originally staged in 2005, and in its third revival this year, has a cast without a weak link, and never fails to draw in the audience to the work’s cycles of power, suffering, death and intermittent triumph. It brings us deep into the mind and essence of every character. And holds us right there.

Stumble across Grange Park Opera’s new brick-clad “Theatre in the Woods”, nestled amid a labyrinth of gardens and orchards next to the rambling Tudor pile of West Horsley Place in Surrey, and on a mild June evening you may feel as if you have fallen into some Home Counties version of a magic-realist novel.

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.
