Quantum mechanics and avant-garde music both have in common a pretty steep learning curve. So it shows considerable character from the London Sinfonietta, 50 this year, to take both on in an evening of music and experiments at Kings Place (part of the latter’s Time Unwrapped series). The evening had two parts: a lecture and demonstration from Jacksonian Professor of Natural Philosophy Malcolm Longair, a Cambridge physicist who played his part as ruffled don to perfection, and then music from pianist Rolf Hind, soprano Elizabeth Atherton and players of the London Sinfonietta. Webern, Berg, Schoenberg, Debussy and Cowell were on the programme, their pieces roughly contemporaneous with the remarkable decade in which Albert Einstein wrote his papers on special and general relativity, 1905-1910.
We were there to learn about (musical) spacetime. I could probably understand about thirty percent of what Prof. Longair was talking about when it came to the physics, but this wasn’t really the point: he and his assistant ran experiments using lasers and demonstrated the nature of Einstein’s (and others’) insights using mirrors and lenses that distorted and bent images of galaxies and stars. You could do all this as a programme note, I suppose, but where would the fun be in that? And there was a more serious payoff to this as well: the experiments – we were told to clap louder if they went wrong – helped to drive home a feeling that the music we would hear after the interval had a contingent, risky character too, adventures in the musically thinkable whose meaning might only be glimpsed obliquely.
Anton Webern’s Drei Lieder are masterpieces of compression, presaging in their brevity the stringent, crystalline music of gesture manifested in his later serialist works. Here we could hear these same dramatic gestures, though embedded in the lusher and richer sonorities of late Romanticism, albeit in brief. Elizabeth Atherton gave us an Isolde in miniature, singing with clarity of diction and immediacy that meant nothing was wasted.
This was followed by equally, well, rapturous singing in Schoenberg’s setting of Stefan Georg’s Entrückung (“Rapture”), that concludes his Second String Quartet. “Ich fühle Luft von anderem Planeten”, the soprano sings, as the strings hold a high, gently shimmering chord: I feel the air from another planet. The principal strings of the London Sinfonietta provided enough bite and sparkle to set the scene for this blast of cosmic poetry, floating through the upper registers of their instruments, pulling us free of conventional harmony’s gravitational force into a new musical universe.
