How do you render pure goodness interesting? Unorthodox director Dmitri Tcherniakov and radiant young soprano Svetlana Ignatovich make us smile and break our hearts with their take on the maiden Fevroniya: living at one with nature, seeing God in everything and destroyed by her encounter with civic life.

Where to start? We at The Grange Festival began in mid-March (the 15th) with a letter to our company, all those few hundred who come and work for us during the festival months and who are all, almost without exception, employed on a freelance basis, warning of a likely cancellation but urging a commitment to stage the summer festival over June and July (with preparations stating in mid-April) if at all possible.

Russia came late to the coronavirus lockdown, and will be leaving early – this evening Vladimir Putin announced that national measures were coming to an end, though the disease still rages there.

Liberated from Pushkin’s salons, ballrooms and bedrooms, Barrie Kosky’s Eugene Onegin bursts out into nature. Tatyana and Olga lounge in the long grass stealing heavy fingerfuls of jam straight from the jar; party-guests run through the trees with flaming torches, dancing wildly, barefoot; after the harvest groups gather on the lawn with picnics and games. This is a world apart, the hot, hazy, endless summer of first love – an intense, but unreliable memory.

So many of the world's great opera singers inviting us to look through the keyhole at a carefully presented version of their lockdown lives over four very variable hours, such bad sound for the most part (Skype, like Zoom, catches the voice but loses the accompaniment).

Inventiveness waxes ever stronger, it seems, in quarantine, as do the number of faces and instrumental sounds gathered together at any one time.

A brutal Greek tragedy and a rococo Viennese comedy, both filtered through the eyes and ears of 20th century genius: what a feast on consecutive nights from the Metropolitan Opera's recent archive. There's been real thought behind the wealth of programming in the company's attempts to keep the world happy for free during lockdown, including a whole Wagner week.

Wagner's final drama, of learning, suffering and redemption through compassion, is second only to Bach's Passions at this time of year, and seems likely to strike a special note in the present crisis. Opera companies around the world, making much in their archives free to view right now, have served up the natural seasonal choice, and they have: there are at least nine choices right now, and they come from the expected centres of excellence including Berlin, Vienna, Munich, New York.

One way to look at Stravinsky's celebrated collaboration with W H Auden and Chester Kallman is as a numbers opera in nine pictures, four of them indebted to Hogarth's series of paintings/prints.

Feeling stir-crazy right now? Imagine being confined to one room with a half-crazed housekeeper, two dysfunctional kids and two increasingly insistent ghosts, plagued by nightmares, unable even to get out into the garden or walk down to the lake.
