How A.I. Is Creating Building Blocks to Reshape Music and Art<br />Using neural networks, he and his team are crossbreeding sounds from very different instruments — say, a bassoon<br />and a clavichord — creating instruments capable of producing sounds no one has ever heard.<br />As Mr. Eck says, these systems are at least approaching the point — still many, many years away — when a machine can instantly build a new Beatles<br />song or perhaps trillions of new Beatles songs, each sounding a lot like the music the Beatles themselves recorded, but also a little different.<br />“This is a totally new aesthetic.”<br />In 2015, a separate team of researchers inside Google created DeepDream, a tool<br />that uses neural networks to generate haunting, hallucinogenic imagescapes from existing photography, and this has spawned new art inside Google and out.
