Gounod's Faust is many things: vaudeville act, sentimental romance, Gothic tragedy, Catholic catechism, in short, a wholly unrealistic but winningly schizophrenic work that should be taken about as seriously as an episode of Sunset Beach. Director Des McAnuff's attempt to marshal this melodrama into revealing truths about Nazism, war crimes and the morality of modern science was always going to be a bit ambitious.

I suppose it was inevitable after their magnificent high with Meistersinger in the summer that Welsh National Opera’s next production in Cardiff’s Wales Millennium Centre would be a let-down. But one hardly expected a crash-landing quite as spectacular as their new Fidelio, which looks, sounds and feels like a show thrown together with a scratch cast, a weary orchestra, and a director who was shown the score for the first time last Tuesday.

There’s something deliciously extravagant about this Pinocchio by composer Jonathan Dove and librettist Alasdair Middleton. It’s remarkably faithful to Carlo Collodi’s picaresque text, and so we get everything. Elaborately costumed characters enter with spectacular props, then disappear having barely made their point, my favourite being the four top-hatted black rabbits who threaten to escort Pinocchio offstage in a coffin after he’s refused to take his medicine.

Anticipating revivals of productions that were hardly vivacious in the first place, you can always find reasons to hope. Perhaps there'll be a dazzling house debut. Maybe someone, preferably the revival director, will bring a more focused individual zest to the kind of rough character sketches Jonathan Miller leaves flailing around his beautifully conceived historic locales. Not on this occasion.

From the cuckoo hidden somewhere in the Albert Hall thicket to the Wagnerian bacchanalia of a rollicking Witch's Ride, Glyndebourne adapted its queasy little fairy tale to the widescreen of the Proms with its usual style. There was a twist or two to the consumerist heaven and hell of Laurent Pelly's never too heavy-handed production as semi-staged by assistant director Stéphane Marlot. And centre-platform rather than down in the pit, the phenomenally gifted Robin Ticciati played Peter Pan to the best possible pair of "children", helping them to soar in Albertspace with effortless charm.

Forget Dan Brown’s phony grail trail which has led so many paying pilgrims to Rosslyn outside Edinburgh. For the last week of the Festival Fringe the Chapel, most intricate and mysterious of 15th-century sanctuaries, has become a temple of high art dedicated to Mozart, Shakespeare and Britten. Ambitious indeed of a bunch of Cambridge undergrads and alumni to mount The Magic Flute and the operatic Midsummer Night’s Dream side by side. Did they pull it off? Just, in the case of the Britten, which is saying something given a score which is...

Nobody knows any real happiness, and human kindness is rarely to be found, in Dmitri Tcherniakov's Bolshoi production of Tchaikovsky's "lyric scenes" - the most disciplined and real piece of operatic teamwork I've seen ever to come from the Russian establishment. Hollow laughter and senseless mirth envelop the traumatised, semi-autistic Tatyana of Ekaterina Shcherbachenko, one of two perfect heroines in this double-cast run and worthy of the fuss that surrounded her dewy triumph as 2009 Cardiff Singer of the World.

Thirty-five years on and this is still as much David Hockney’s Rake as it is Stravinsky’s or W H Auden’s. How rarely it is that what we see chimes so completely and utterly with what we hear. The limited palette of colours, the precisely etched cross-hatching, the directness and the cunningly conceived elements of parody – am I talking about Hockney or Stravinsky? Two great individualists in complete harmony. So why the disconnection?
