Composing music by algorithm

Via KurzweilAI.net — Very interesting, and I can see where composers would be concerned, but I think Cope’s getting a little ahead/full of himself with the final quote about computers, humans and soul. Hopefully the quip was tongue-in-cheek that just didn’t translate to print.

Triumph of the Cyborg Composer
Culture & Society, Feb. 22, 2010

David Cope’s algorithmic compositions rival the beauty of music by human composers and have passed the musical equivalent of the Turing Test (listeners cannot determine which music is human-composed). They herald the future of a new kind of musical creation: armies of computers composing (or helping people compose) original scores, he believes.

But some — especially composers — are threatened by the ability of artificial creativity programs to compose works fast that are good and that the audience likes.

Undeterred, Cope thinks humans are actually more robotic than machines. “The question,” Cope says, “isn’t whethercomputers have a soul, but whether humans have asoul.”

Creativity in action

Here’s a very cool bit on whether creativity makes you happy.

I love this description here. I’ve been there writing fiction at times.

Early in the talk, Csikszentmihalyi presents us with the following description by a leading composer, of his experience while composing music:

You are in an ecstatic state to such a point that you feel as though you almost don’t exist. I have experienced this time and time again. My hand seems devoid of myself, and I have nothing to do with what is happening. I just sit there watching it in a state of awe and wonderment. And [the music] just flows out of itself.

This sounds like a mystical experience, yet Csikszentmihalyi offers a scientific explanation. Apparently our nervous system can only process about 110 bits of information per second. Listening to someone speak takes up about 60 bits of neurological ‘bandwidth’, which explains why we can’t listen to more than one person at a time. Because the composer is concentrating so hard on his music, he is using all his available bandwidth and there’s none left over to monitor his sense of self:

when you are really involved in this completely engaging process of creating something new – as this man does – he doesn’t have enough attention left over to monitor how his body feels or his problems at home. He can’t feel even that he’s hungry or tired, his body disappears, his identity disappears from his consciousness because he doesn’t have enough attention, like none of us do, to really do well something that requires a lot of concentration and at the same time to feel that he exists.
