This is blowing my mind. This is Darwin Tunes. Fast forward to around 3:00. You hear what sounds like a palatable keyboard song. With rhythm and progression and all. Go back in the song and you can see how the song literally evolved. A computer program created bits of noise that adapted to the preferences of thousands of users. And in the end it produces some pretty decent music. I mean, a bit like a dude in the subway on a synthesizer, but a talented, cyborg dude.
The experiment began with 100 randomly generated loops. On the DarwinTunes website, listeners could listen to these and rate them on a five-point scale, from “I can’t stand it” to “I love it”. Every time 20 loops were rated, the top 10 pair off, mate with each other to produce two daughters, and die. At any time, there are only 100 loops in the total population.
To date the loops have been evolving for 3,060 generations, and over 50,000 of them have been born. By taking loops from DarwinTunes’ entire history and asking volunteers to rate them, MacCallum and Leroi showed that they became more appealing with time. For example, they were more likely to contain chords found in Western music and they contained more complex rhythms. (Discover Magazine, via Andrew Sullivan).
Kinda awesome and kinda trippy. Combine this artificial intelligence with pubescent teen avatars and you would get… Carly Rae Jepsen. Or a robot Justin Bieber. Oh God.
