Does great music require a great composer? It seems not...

Professor Armand Leroi from Imperial College London believes that music evolves in the same way that nature does...and it looks like he may have a point.

Together with Dr Bob MacCallum, Leroi used a computer system called DarwinTunes to evolve music from randomly geneated noise.

Two randomly generated loops were allowed to "breed", recombining and remixing material until 100 distinct tunes had been created. Volunteers were then asked to rate the tunes, with the favourites being allowed to continue "breeding"...after thousands of such generations, the material produced was sounding good.

Leroi says: "I've no doubt that if we ran this experiment for longer...we could evolve fantastic music...it would just be the people's music in its purest form."
