OpenAI’s MuseNet generates AI music at the push of a button

OpenNet's MuseNet is a new online tool that uses AI to generate songs with up to 10 different instruments. Not only that, but you can create music in up to 15 different styles, imitating classic composers like Mozart, contemporary artists like Lady Gaga or genres such as bluegrass or even videogame music. You can start with a short segment of the music to start or start from scratch.

MuseNet works using a deep neural network that has been trained in a set of MIDI file data collected from a variety of online sources covering jazz. Styles of pop, African, Indian and Arabic music. The researchers behind the project say that the system can pay attention to music for long periods of time, which means that it is able to understand the broad context of the melodies of a song, rather than how they flow together in a short section. With this data, the system has the task of predicting the next note in a sequence.

When you test it for yourself, you can hear this approach at work. Give MuseNet some music to start, and initially follow the style very closely. However, as the music progresses, the predictions of the AI ​​deviate more and more from the original. When I did write the end of the song Harry Potter in the style of a video game soundtrack, it finally became the subject of nightmares.

The software is just the latest OpenAI project, which recently made headlines to produce an AI capable of defeating the world champion electronic sports team at Dota 2 . The same AI was later released in the audience that played Dota with devastating results. The other OpenAI projects have been able to write convincingly by ingesting a large number of articles, blogs and websites.

OpenAI is not the first company to experiment with music generated by AI. Taryn Southern released an album completely composed with AI in 2017, and other musicians are experimenting more and more with the use of artificial intelligence in their composition process. But this new wave of AI composition raises some complicated legal issues about who owns music rights, and the problem is only going to get worse as tools like MuseNet reduce the entry barrier of AI composition.

MuseNet is available to try now on the OpenAI site, where you can also listen to a selection of songs that the team has already generated and read about how the system works. TechCrunch reports that the generator will remain online until mid-May, after which, eventually, it will be open source.
