"I think that creativity can sometimes come from introducing a randomizing function into the process. It adds errors, which can break up a predictable uncreative effort and lead it into new directions.
This is the reason sleep deprivation, drugs, and illnesses have sometimes produced interesting works of art, and part of what leads artists to use those methods.
I think that this differs from other types of creativity but I can't really support that with any evidence. I would like to say the error method is not true creativity, but that may not be accurate at all. It may just feel different.
As far as execution goes, all drugs seem to make performance worse, with some anecdotal evidence that Diet Coke is the worst. "
Yes, I think this is the case. I am at times desperately inclined to wish it were not so but I rather think it is. I usually fall foul of it with respect to time. I frequently assert that I need more time to play, practice and improvise. Yet when I enjoy many free days in succession I frequently produce nothing - except possibly an improved physical technique. Many things in life do behave in proportion to time and effort but experience tells me that creative ideas in music do not.
Unfortunately, neither is it simply a matter of total caprice and serendipity. I do need periods of pedestrian work, reason and concentration. As with most things in life, there is a critical state of balance which, while containing reason as an essential component, is itself permanently elusive to ratiocination and planning. The whole business probably goes right to the heart of how our minds work.
In the meantime, we would perhaps do well to follow J.B. Priestley, and "start paying attention to the crackpot in ourselves" - the dreams, the visions, those transient peculiar convictions which the "nothing but" men tell us to ignore. Speaking for myself, I am both mystic and rationalist. I suppress neither, because somehow I think their interaction lies at the heart of my music.
