The BBC put social and ethnic diversity at the heart of this Last Night programme. The concert opened with a new work, by Daniel Kidane, called Woke, and the first half was dominated by the music of black and female composers.

A masked ball is a time of play and role-play, celebrating the duality, the conflicting selves within us all, allowing us to set aside our everyday public mask put on an alter ego for the evening. It seems appropriate then that Verdi’s Un ballo in maschera has a deep fissure running down the middle of its drama. Is it a fragile, unfulfilled love story – Rattigan or David Lean with an Italian accent and rather more blood – or is it an exuberant piece of gothic horror with a love story and political agenda tacked on?

What is the perfect country house opera? A Midsummer Night’s Dream? L’elisir? Cenerentola? Figaro? All are strong contenders, but in the absence of anyone brave enough to stage Gerald Barry’s The Importance of Being Earnest the winner – surely – must be Falstaff.

Opera North created something approaching a new art form when they performed Wagner’s Ring in "concert stagings", putting their large orchestra in full view, with singers symbolically dressed and given limited front-of-stage space, and a continuous projected screen backdrop.

This will be the latest in Opera North’s acclaimed concert stagings of large-scale works, which have previously included Wagner’s Ring cycle, Puccini’s Turandot and Strauss’s Salome.

A crash, a scurry, a long, lilting serenade – the overture to Rossini’s Elizabeth I sounds oddly familiar. Not to worry. English Touring Opera has anticipated our confusion. “You may recognise this overture” flash the surtitles, to a ripple of laughter, before explaining that yes: this is essentially the same piece, originally composed in 1813 for Aureliano in Palmira that ended up attached to – of all things – The Barber of Seville.

When "Maestro" Riccardo Muti left the Royal Opera's previous production of Verdi's fate-laden epic, disgusted by minor changes to fit the scenery on the Covent Garden stage, no-one was sorry when Antonio Pappano, the true master of the house then only two years into his glorious reign, took over. He's now unsurpassable in the pace and colouring of the great Verdi and Puccini scores.

Would Verdi and Puccini have composed more non-operatic music, had they thrived in a musical culture different to Italy's? Hard to say. What we do know is that they both became absolute masters of orchestration – Puccini rather quicker than Verdi, living as he did in an entirely post-Wagnerian era.

Why is Un Ballo in maschera not as popular as the trio of Verdi masterpieces – Rigoletto, Traviata, Trovatore – that, with a couple of digressions, preceded it in the early 1850s? Its music is scarcely less brilliant than theirs, and if its plot is on a par of absurdity with Trovatore’s, it is at least, on the whole, more fun. One problem might be a certain thinness in the portraiture, as if Verdi was more interested in the incidents than in his characters.

Political machinations and backroom power-brokering, leadership battles and unscrupulous rivals – if ever there was an opera for this week it’s Simon Boccanegra. Premiered in 1857 but only coming into its own after substantial revisions in 1881, Verdi’s problem-child of a piece had its own struggle for survival and success, and the work’s rather lumpy dramatic architecture shows the scars of its various grafts and interventions.
