William Byrd, Arnold Schoenberg and their respective acolytes go cheek by jowl, crash into one another, soothe, infuriate and shine in their very different ways This is all in a typical programme of pianist, conductor, composer and all-round pioneer Karim Said, and last night in the studio of Leighton House, it nearly all worked (when it didn’t, that was the nature of the beast, not the pianist).

This looked like a classic Prom in the grand old BBC tradition: two big but lesser-known pieces by pivotal figures (Schoenberg and Zemlinsky) played by a major non-metropolitan ensemble, the BBC National Orchestra of Wales. And so it proved, with powerful, refined and meatily satisfying versions of Arnold Schoenberg’s Pelleas and Melisande and Alexander von Zemlinsky’s The Mermaid conducted by the NOW’s chief, Ryan Bancroft.

For musicians, the period from early 2020 to mid-2021 was one of great reflection, with so many questions to puzzle over. Could we satisfy the basic need to interact with others and express ourselves? What on earth was Zoom, and how, as performers, could we learn to use technology to provide live experiences? Would things ever go back to the way they were? And should they?

Schoenberg’s “Song of the Wood Dove” takes up a mere 11 of the 100 minutes of his epic Gurrelieder, though it’s a crucial narrative of how King Waldemar of Gurre’s beloved Tove was murdered by his jealous queen. Last night, as in Simon Rattle’s 2017 Proms performance, stunning mezzo Karen Cargill came on stage, immediately in character, and with no reference to the score on the stand in front of her, showed everyone else how to do it.

Christian Gerhaher and a string ensemble led by Isabelle Faust presented here a programme of works with a nocturnal theme. Gerhaher’s voice is an instrument of husky shadings and dark hues, so the night theme seemed wholly appropriate.

Barrie Kosky’s production of Moses und Aron was staged at the Komische Oper Berlin in 2015 to mark the 70th anniversary of the liberation of Auschwitz. Schoenberg’s opera is philosophical and open to a variety of interpretations.

Only a modest audience turned up for this BBC Symphony Orchestra concert, though it was unclear if this was caused by the threat of airborne disease or the inclusion of Schoenberg on the programme. The result was a paradoxical intimacy, with the huge orchestra expressing complex but private emotions from a group of fin de siècle Viennese composers.

The big news on this programme was Schoenberg’s Pelleas and Melisande. This early score, completed in 1903, is a sprawling Expressionist tone poem, making explicit all the passions in Maeterlinck’s play that Debussy only implies. The story plays out through a handful of chromatically complex Leitmotifs, but such technical considerations are soon overwhelmed by the sheer urgency of the musical drama.

At first sight, performing Stravinsky’s The Rite of Spring – premiered in 1913 and sometimes seen as presaging the whole world of modernism – in the centenary year of the 1918 Armistice might seem to be lagging behind in timing (if centenaries float your boat).
