It takes a few key ingredients to create music: a format to record the notes, like a pen and paper or a computer program, a way to play these notes and a composer. However, professor Armand Leroi thinks you can skip one of these ingredients. “What we are trying to find out is whether you need a composer to make music. And we don’t think you do.”
Leroi and his colleagues at Imperial College London have designed a system of composition that works like Darwinian evolution. Listeners get to vote on different sounds, the ones that they like become part of the the composition and evolve with other sounds that were also liked. Sounds that do not please the listeners are eliminated and so it becomes survival of the most listenable sounds.
