Magneta, a Google research team, has developed Piano Genie, an artificial intelligence-powered interface that lets anyone improvise on the piano using just eight buttons. The researchers were inspired by Konami’s Guitar Hero, a rhythm game, and rather than have users play actual songs, they wanted them to create their own melodies in real-time, which is made possible by an AI trained on a large data bank of classical piano music, thus enabling the AI to predict what notes follow each other.

The main component is a recurrent neural network, a type of program that’s particularly good at learning to mimic sequential data, such as writing and music. This neural net was fed with a dataset of piano music taken from an international competition. This data was particularly useful, as the competition records all performances in a file format that preserves not only the notes, but also velocity,” reports The Verge.
