Baptiste (BBC One) has two powerful weapons in its armoury, in the shape of its stars – Tchéky Karyo as the titular French ‘tec, and Fiona Shaw as the central character in this second series. Both of them are astonishingly persuasive at conveying unfathomable depths of pain and loss, and it looks like they’ll have plenty of opportunities to prove it across these six episodes.

In verses from the folk anthology Des Knaben Wunderhorn (The Youth's Magic Horn) set by Mahler as a song, later adapted for the scherzo of his Second Symphony, St Anthony of Padua sermonizes on repentance to the fish, who all listen politely and then carry on behaving as they did before.

Poulenc’s La voix humaine comes close, but Bartók’s Bluebeard’s Castle has to be the perfect lockdown opera, this heady tale of two mismatched souls stuck in a confined space (admittedly an enormous one) alarmingly pertinent.

And then there’s the luxury free gift that Sir András Schiff bestowed on us during the second of two Barbican concerts with Iván Fischer and his Budapest Festival Orchestra.

Mozart’s piano concertos often overflow with good humour, but you seldom expect to hear a hearty chuckle from the audience in the middle of a performance of one. Yet something close to a guffaw burst out around King’s Place when soloist Tom Poster, deep into the last-movement cadenza of Mozart’s Piano Concerto No. 19 in F major, suddenly quoted Gershwin’s Rhapsody in Blue. Poster had played the Gershwin before the interval of this typically smart, eclectic and thought-provoking programme from the Aurora Orchestra under Nicholas Collon.

Bartók: Complete String Quartets Quatuor Diotima (Näive)

When critics praise a first-rank string quartet, convention demands they claim that the whole adds up to more than the sum of its parts. True enough, maybe, but with the Takács Quartet, each separate element really does blaze with a soloistic, virtuosic flame. From the first bars of last night’s opener at the Wigmore Hall, as Haydn plays pass-the-parcel with an apparently straightforward tune at the start of his G major quartet Op.76 no. 1, the sheer class and distinctive voice of each instrumental contribution grabbed the ear.
