From software developer and writer Tero Parviainen, an interactive presentation on how generative music works. (Roughly speaking, generative music is "about making music by designing systems that make music".)
The presentation includes many examples — Terry Riley's In C, Brian Eno's recent app, Listen to Wikipedia, Steve Reich's work, neural nets for generating music — and a few interactive generative music toys you can play around with. (via waxy)
