I’m not sure for what reason, perhaps the turmoil of our age that preoccupies me, but of late, I’ve been drawn more than usual to the idea of the invisible world around us. Never of a religious bent, yet, for as long as I can remember, I’ve been drawn to thinking about the unseen world that is all about us. It was Blake who said it most simply – to see a world in a grain of sand – and Rilke, who to my mind, comes always the closest to evoking a sense of the swirl of life all around us that we don’t see. Such thoughts have also drawn me to reading (without much understanding) so many books about particle physics, as it pleases me to imagine the countless particles streaming invisibly through the universe – through me – and passing through all matter without obstacle. And, music, it goes without saying, is the medium that I believe best communicates these feelings. Overtones, for example, with their simple physical explanation, will yet always seem magical, the invisible world at work in the visible (or audible) world. Although never evident to our senses, it is all that is real, and the everyday nonsense that so arouses everyone’s passions that is illusion. It is this hidden world that I seek to convey, to the extent of my ability, with my music.
