What is a symphony? It’s always been a very elastic term, with no fixed rules about its form or content. It can be a ten-minute piece for just a few instruments, or a monumental work of an hour or more in length, for a large orchestra. Royal Northern Sinfonia, directed by Conductor Laureate Thomas Zehetmair, explored both ends of the symphonic spectrum, drawing their examples from Zehetmair’s native Austria.
For an example of a short symphony, a safe programming choice might have been Haydn, but instead, Zehetmair gave us an exquisite little jewel by Webern: the Op.21 Symphony, which is just ten minutes long, and scored for an orchestra that’s little more than a chamber ensemble – strings with harp, clarinet, bass clarinet and two horns. It is very carefully structured, full of architectural elegance, and although the casual listener probably needs to have the score in hand to appreciate the full complexity of Webern’s symmetries, this graceful performance gave a clear sense of the structural bones. Each instrument contributes their part in sparse fragments, yet RNS joined everything up seamlessly, with a clear beat running through the disjointed parts. Zehetmair carefully unfurled the first movement from its microscopic opening, before disappearing back to where it came from, whilst in the quirky second movement the introversion gave way to an odd little waltz with a playful ending.
Webern was part of the Second Viennese School, whose spartan compositional style emerged as a reaction against the expressive excesses of late Romantic composers such as Mahler. As a chamber orchestra, RNS is too small to give us the full Mahler symphony experience, but we had a taster in the form of the Adagietto from his Fifth. Zehetmair kept the opening very still, with barely a ripple of vibrato, then allowed the strings sudden surges of passion that came from nowhere in shuddering gasps, before dying back down. This was a struggle between dark and light, but as the absolute calm of the opening returned, the players brought with it a sense of peace and resolution and, in this version as least, the light had won.
Carl Philipp Emanuel Bach wrote a number of symphonies, but tonight we heard instead one of his oboe concertos (in B flat major), with principal oboe Steven Hudson taking the solo. The outer movements were delightfully sunny, with Hudson giving the oboe part an easy fluidity, and playing an amusingly flirtatious game with the orchestra in the third. In contrast, the middle movement was deeply expressive, with lovely subtle shadings of dynamics, and with all the embellishments tenderly enhancing the underlying musical line.
