Computer Program 'Evolves' Music From Noise - ScienceNOW

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.

That is the larger temporal structure of well-formed musical pieces is composed of repeating motifs of their own short-term temporal structure.  At the same time, researchers also discovered that each composer had his or her own highly individual rhythmic signature. “This was one of the most unanticipated and exciting findings of our research,” asserts Levitin. “Mozart's notated rhythms were the least predictable, Beethoven's were the most, and Monteverdi and Joplin had nearly identical, overlapping rhythm distributions. But they each have their own distinctive rhythmic signature that you can capture.
