Sonic youth

Everyone knows — don’t they? — that the National Youth Orchestra of Great Britain is the UK’s youngest world-class symphony orchestra — an ensemble of musicians aged 18 and under that’s the equal of any professional band (and better than some). But it’s also the largest, and we don’t hear enough about the sheer sonic impact of hearing 157 musicians moving with absolute precision. Even the smallest gesture by an 87-player string section has a sort of heft, a physical weight and depth that you can sense in the air around you. Overwhelming when the whole orchestra is playing at full power, it’s even more tangible in quiet passages, as if you’re in the vicinity of some vast, invisible living creature.

It was a neat idea, then, for director Daisy Evans to make the orchestra into a character in the NYO’s concert staging of Bartok’s Duke Bluebeard’s Castle, namely the massive, semi-sentient presence of the Castle itself.
