Computer Program 'Evolves' Music From Noise - ScienceNOW: ...adapted DarwinTunes to be accessed online by almost 7000 participants who rated each sound loop, played in a random order, on a 5-point scale from "can't stand it" to "love it." In a musical take on survival of the fittest, the highest-scored loops went on to pair up with others and replicate. Each resulting generation was rated again for its appeal. After about 2500 generations of sound loops, what started out as a cacophony of noise had evolved into pleasant strains of music.
