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

I started singing when I was nine years old in my primary school choir. I sang plenty of solos there before moving on to another children’s choir; that was a formative experience for me. At this point, I was singing the soprano part and from here I was invited to sing in Mozart’s The Magic Flute. This was my first experience of opera, and one that gave me great joy and satisfaction.

Inevitably, the story begins and (almost) ends with Las Meninas. Inspired by the art and life of Diego Velázquez, Amy Sackville tops and tails her third novel with his endlessly enigmatic group portrait from 1656. It shows the Spanish royal household, their dwarves, a mastiff, a perplexing reflection of the King and Queen in a mirror – and the court painter himself, trapped forever in this nest of “sometimes impossible frames”. The painting ensnares us in a hall of mirrors, a labyrinth of gazes.

Held annually every Holy Week, Kraków’s Misteria Paschalia is one of the continent’s most vibrant early music festivals. With an increasing focus on international collaborations, the 2018 edition welcomed Edinburgh’s Dunedin Consort as artists in residence, and their director, Professor John Butt, as Resident Artistic Director.

Vivaldi’s The Four Seasons: A Reimagining – it’s not a title that trips off the tongue. Nor one, frankly, that inspires much excitement, with its clunky functionality and on-trend buzzword. But set that aside and buy a ticket immediately, because Gyre & Gimble have made magic with their latest show.

It was the work with which Handel conquered London, the Italian opera that finally wooed a suspicious English audience to the charms of Dr Johnson’s “exotic and irrational entertainment”. Three hundred years later, neither Rinaldo nor London’s audience has changed much.

The advertising for La Nuova Musica’s Orlando billed it as “Handel’s most psychologically complex opera”. Whether or not you agree (and there are plenty of heavyweight rivals – Alcina, Giulio Cesare and Agrippina just for starters) there’s also the issue that it’s only half the story.

Cheers and huzzahs greeted the arrival of Sir Simon Rattle on the Barbican stage last night before the London Symphony Orchestra had even played a note. The 10-day festivities to open his tenure as principal conductor evidently worked a treat. The hall was full for a lengthy and – on the surface of it – unlikely splicing of Austrian Romantic angst with Baroque arias and dance.

In 1725 a collection of some 50 songs was published by one William Thomson. You might not know his name, or even the names of the songs, but given the first bar of most I’m betting you could hum them from beginning to end. The work? Orpheus Caledonius – the first published collection of Scottish folk melodies and lyrics.

Amazingly, last night Sir András Schiff scored a Proms first with his performance of Book One of Bach’s The Well-Tempered Clavier. Never before has even half of the sublime and seminal “48” taken the Royal Albert Hall stage in unmutilated form. The WTC could have found no better advocate.
