I don’t have a personal style as such – although I am sure there are recurring tricks if you look for them. Writing a piece is finding a solution to a problem, and when the initial restrictions vary, so does the end result. But when I write a piece like ‘Not Now, Bernard’, which is very tuneful and ‘accessible’, I don’t think of it as any less a ‘proper piece’ than my more avant-garde pieces – they are all aspects of my compositional voice.
