What matters in modern music is not the part you can write down, the words and the tune, but the rest - the texture, the atmosphere, the references and associations.
Brian EnoIn fact, quite a lot of what I do has to do with sound texture, and, you can't notate that. You can't notate the sound of "St. Elmo's Fire." There's no way of writing that down. That's because musical notation arose at a time when sound textures were limited. If you said violins and woodwind that defined the sound texture; if I say synthesizer and guitar it means nothing - you're talking about 28,000 variables.

That is to say, I tend towards the roles of planner and programmer, and then become an audience to the results
Brian EnoThe Marshall guitar amplifier doesn't just get louder when you turn it up. It distorts the sound to produce a whole range of new harmonics, effectively turning a plucked string instrument into a bowed one. A responsible designer might try to overcome this limitation - probably the engineers at Marshall tried, too. But that sound became the sound of, among others, Jimi Hendrix. That sound is called electric guitar.
