Reaching the Tippett point
In Oliver Soden’s new biography of Michael Tippett, he describes how Tippett wanted to open his Fourth Symphony with the sound of breathing: ‘as if the orchestra itself had lungs.’ Tippett had no idea how to achieve this effect, and at the première in 1977 they used an orchestral wind machine — a canvas band rubbing against a wooden drum. It proved about as convincing as it sounds, so at later performances a musician exhaled down a microphone. The effect, writes Soden, was reminiscent of an obscene phone call.
