A few months ago I shoved my brain into a multi-million pound electro-magnetic scanner at a research hospital in Sheffield so that Professor Lawrence Parsons, a cognitive neuroscientist, could discover what was going on in my head when I was listening to and playing music. He particularly wished to know what was happening in my hippocampus – the region of the brain that is concerned with musical memory and experience. For a week he pored over the results only to prove, in the end, that I was a fake. Comparing encephalograms of my listening to music with images of my playing it, he was able to observe that the emotional part of my brain (that part which was active when I was listening) was completely shut down when I was playing. This it seems, is the same for all musicians. A good pianist may have the skill to reduce his audiences to tears, but he does not achieve this by expending any of his own emotion as he does so. During a concert he simply pulls items from his box of tricks – a clinical, clever process requiring taste and technique, but no emotion.
