God it’s good to laugh in an opera house. Not a hear-how-clever-I-am-to-get-the-laborious-operatic-joke laugh, or an I-realise-this-is-supposed-to-be-funny-so-I’m-playing-along one, but a real, spontaneous laugh that tickles into sound before you’ve even had time to register its approach. Back for its second appearance, Robert Carsen’s Glyndebourne Rinaldo is ingenious and witty, joyous and completely over-the-top, and the best possible ending to this year’s summer opera season.

The sprightly tread of Handel’s Queen of Sheba, attended by two wonderful Turkish oboists, wove the most fragile of gold threads between full orchestral exotica and Rameau motets of infinite variety last night. Not that any more links need be found: it’s the addition of the late night events which turns the Proms into a real festival, not the mere concatenation of concerts you might find in the main orchestral season.

I felt so shocked by the events that took place during the premiere of Handel’s Ariodante on 3 July in the Festival d’Aix-en-Provence last week, and so disappointed that our painstaking work with director Richard Jones over the last six weeks had been so comprehensively ruined, that I felt I should document what happened.

The latest in a series of "Pinnock’s Passions" concerts at the Sam Wanamaker Playhouse saw the doyen of period instrument performance lead a delightful exploration of Handel the musical borrower, entitled "Handel’s Garden". As Trevor Pinnock writes in the programme notes, "throughout his life as a composer he had the habit of taking cuttings, transplanting and grafting from works old and new".

This was smart programming. The final night of London's Lufthansa Festival of Baroque Music presented the forces of the Göttingen Ha(e)ndel Festival.

The last time the BBC dramatised the creation of a great musical work, it didn’t quite hit the spot. Eroica starred Ian Hart as Beethoven glowering at the heart of a drama which had rather less of a narrative through-line than the symphony it honoured. For Messiah at the Foundling Hospital, the BBC have gone to the other extreme and kept eggs out of the one basket. There was a bit of drama, a bit of documentary, some costumed musical performance and there were even two presenters to come at the story from opposite angles.

If they asked me, I could write a book about the way one number in Richard Jones’s ENO production of Handel’s Rodelinda – the only duet, after 18 arias, and nearly two hours into the action – looks, sounds and moves.

Oslo is a winter wonderland, and adults seem to be outnumbered by children, flocking from all over Norway to Disney on Ice. It’s the deep snow and the silence in pockets of the city rather than the kids which make me wonder if anyone has set Handel’s Alcina in the icy lair of C S Lewis’s White Witch, with hero Ruggiero as Edmund fed Turkish delight from the magic phial. There's even a captive lion. Francesco Negrin’s straightforwardly magical production - look, no metatext!

The Barbican’s ongoing season of baroque operas and oratorios has been a mixed bag.  Most recently The Sixteen’s Jephtha was a rather lacklustre affair, leaving me nervous of committing to the many hours of Handel’s beautiful (but protracted) Theodora. But I needn’t have worried. Harry Bicket and The English Concert gave this late work all the pep and personality that was so lacking last week, driving it through its rather uneven acts to a conclusion of sudden pathos and beauty.
