Is The Cunning Little Vixen a jolly children’s pantomime, or is it a searching study of issues of life and death, Man and Nature? The answer, naturally, is that it’s both. Children dress up as animals, and sing and prance about. But at the same time grown-ups (both animal and human) dream and fantasize, couple and procreate, hunt and kill. Remarkably, it’s a tragedy that leaves no bitter taste. The heroine dies, but Nature goes on. The hardest thing to understand about hunters is that they identify with and even love their prey.

On the itinerary of musical tourists around Europe, the opening of the Prague Spring Festival comes a close third to the Vienna Philharmonic’s New Year's Day Concert and the Bayreuth experience. That said, Smetana's Má vlast (My Homeland) – the immoveable opener – is more of an acquired taste than Johann Strauss or Wagner.

Janáček's lacerating music-drama of love-led sin and redemption in a 19th century Moravian village is the opera I'd recommend as the first port of call for theatregoers wary of the genre. Its emotional truths are unflinching, its lyricism as constantly surprising as the actions of its characters are often swift and violent. In the opera house, I've never seen a performance that didn't turn its audience inside out.

Even at the tragic heart of Janáček's Jenůfa there is ambiguity. As the Kostelnička or village sacristan takes her stepdaughter Jenůfa’s baby boy outside to drown it in the icy river, you cannot quite be sure whether she is motivated by pride, fear or her love for Jenůfa. In this poised new co-production by Scottish Opera and Danish National Opera, there is no doubt that she is driven by love. Murderous it may be, and it will nearly destroy her, but her compassion cannot be denied.

With tickets only a couple of pounds more than screenings in the Ciné Lumière, back-to-back – sometimes overlapping - concerts by world-class pianists of all ages, and a lively roster of weekend events around the recitals, what more could you ask from the French Institute’s two-and-a-half day festival? Well, perhaps a better and bigger Steinway. The one that can now transform the cinema into a concert hall, and instigated the first It's All About Piano! weekend last year needed bags of restoration, and given the obstinately dull middle register you have to ask, was it worth it?

Where did all the terrific programming energy of last year’s The Rest is Noise festival go? One answer – surprising given the orchestra’s former Friday night lite status – is into a two-concert adventure by the BBCCO. World to Come, World Once Known has been devised by Principal Conductor Keith Lockhart to reflect the Janus-headed phenomenon of music just before, during and after the First World War.

Glyndebourne nature, it seems, runs along as smoothly as the much discussed new wind turbine on the hill. Within the theatre, though, all is flux: director Melly Still and Vladimir Jurowski, conducting an incandescent London Philharmonic Orchestra, show just how flexible it's possible to be with the viciousness and the vivacity in Janáček's kaleidoscope of birth, copulation, death and a redemption of sorts in celebration of the natural order.

When telling a complex musical story, handle with care. Interpreters need have no fear of composers who find selective, tone-friendly angles in their literary sources, like Janáček with Gogol’s Taras Bulba in last night’s searing finale, or Zemlinsky with Andersen’s The Little Mermaid, the saturated climax of the previous evening. But what about Dvořák in oddball, potentially enriching mode, setting every jot and tittle of a folk ballad without actually using words or voices?

Katie Mitchell’s production of what many regard as Janáček’s greatest opera began life 10 years ago on the stage of Cardiff’s New Theatre; and there are times in this revival when you feel its director Robin Tebbutt’s yearning to be back in that constricted environment, so much better suited to the stifling world which destroys the work’s repressed, self-loathing heroine.
