MuseNet works by using a deep neural network that’s been trained on a dataset of MIDI files gathered from a range of online sources that cover jazz, pop, African, Indian, and Arabic styles of music. The researchers behind the project say that the system is able to pay attention to music over long periods of time, meaning it’s able to understand the broad context of a song’s melodies, rather than just how they flow together in a short section.
