Let’s call it Jane Austen fit for the West End, but with opera singers. The fact that it also serves as a fun ensemble piece for students is also very much in favour of Jonathan Dove’s Mansfield Park, with a neatly telescoped and often witty libretto by Alasdair Middleton. Like his latest work, Uprising, a community opera for Glyndebourne staged at the weekend, it presses all the right buttons for the young, while staying within safe and mostly derivative boundaries.

The score is effective, and rewarding to perform, but derivative. The libretto uses every cliché, or truism, about save-the-planet youth activism in the book; it’s didactic, not dramatic. Direction, design and lighting sometimes feel unfinished. Yet as a youth/community opera, Glyndebourne’s latest educational project hits the mark; the commitment of singers and players young and old, professional and amateur, makes the ends justify the means.

Let’s finally face the elephant in the room: the most popular Viennese operetta, packed with hit numbers, no longer works on the stage as a whole. The central party, yes, never more high-energy delight than here, with a cast of 13 and 10 instrumentalists on stage. As for the rest, not even the likes of Richard Jones, Harry Kupfer and Christopher Alden have won a total victory. Davey Kelleher comes closer, but the high jinks can still be wearing in the outer acts.

A year ago, after a deeply disappointing Manon Lescaut at Hackney Empire, I wrote here that English Touring Opera had often excelled in the past, and would do so again. The company hasn’t taken long to prove the point.

Genius doesn't always tally with equal opportunities, to paraphrase Doris Lessing. Opera houses have a duty to put on new works by women composers; sometimes an instant classic emerges. But to revive a music drama that hardly made waves back in 1977? Thea Musgrave’s Mary, Queen of Scots has some strong invention, and whizzes you through historical bullet points so quickly that there’s no chance to get bored. But does it deserve a company giving it their all?

So the Royal Opera had assembled a dream cast, conductor (Edward Gardner) and director (Richard Jones). The only question until last night was whether composer Mark-Anthony Turnage would be at his remarkable best. His operatic journey has been uneven, but one thing is now certain: adapting the first Dogme 95 movie, Festen by Thomas Vinterberg, so shocking at a time (1998) when the issue of child abuse rarely surfaced in drama, has yielded music theatre of flawless pace and range.

Greek myths are all over theatre stages at the moment, their fierce, vengeful stories offering unnerving parallels with events in our modern world. The latest such project is a pithy double bill of opera and dance, both halves (though the first lasts only 20 minutes) featuring the half-man, half-bull Minotaur, and the havoc he wreaks, even in death.

Drained as they are at present of crucial funds, WNO are managing to put on only two operas this spring, and spaced out to the point where it could hardly be called a season. For their new Peter Grimes we must wait till April. Meanwhile we can relish Tobias Richter’s sparkling nine-year-old Figaro, skilfully revived, with a few tweaks, by Max Hoehn.

Who’s in and who’s not – on the secret, the joke, the relationship, the family, the club? That’s the fulcrum of Joe Hill-Gibbins’ ingeniously simple Figaro for English National Opera. A white box and a row of doors supply the only set to speak of for a production less interested in the entrenched tensions of upstairs-downstairs than the shifting alliances and fragile coalitions of a household in flux.

Saturday night could have given us the opportunity to witness the Opera North debut of Canadian soprano Layla Claire at the Grand Theatre, as well as Annabel Arden’s new production of The Flying Dutchman.
