Douglas Eck, the project leader, posted Welcome to Magenta on its website on Jume 1st but had disclosed rather more about the project at Moogfest the previous week. He revealed that the inspiration for Magenta had come from other Google Brain projects, like Google DeepDream, where AI systems were trained on image databases to "fill in the gaps" in pictures, trying to find structures in images that weren't necessarily present in the images themselves. In the Magenta project Eck and his team want to see if, given enough training data, a machine could create music that would be engaging and exciting for a person to listen to. Eck also suggested that computer-created music could be used therapeutically, suggesting a scenario in which a person's wearable device tracking her heart rate sends a signal to her smartphone that she is stressed and an AI system could generate appropriately soothing music to alleviate the stress.
