Taking a step back from manual production, many artists now employ artificial intelligence in the music-making process. From composition apps and mastering platforms to song-identifying tools and highly personalized playlists, AI is changing the way music is created and heard.

AI Music

AI generates ever-shifting soundscapes designed for relaxation and focus, powers recommendation systems in streaming services, helps smooth audio mixing and mastering, and generates rights-free music without copyright issues. It’s also maturing as a compositional tool, with artists leveraging AI to generate new sounds derived from all manner of audio inputs.

 

AI Music: Artificial Intelligence and Music Generation and Composition

More than 25 years after Kurt Cobain’s death, a new “Nirvana” song was posted online. Why the scare quotes? The track wasn’t actually some long-lost recording from the seminal grunge trio’s active era, unearthed from the vaults. Dubbed “Drowned in the Sun,” it was the product of two AI frameworks: Google’s Magenta, which was used to produce the music, based on input data of dozens of original Nirvana recordings, and a neural network that generated lyrics, which were then delivered by the singer of a Nirvana tribute band.

The track really does sound a lot like Nirvana — the loud-quiet-loud dynamics, the fill-happy drumming. True, the audio is a bit muddy, but the generative complexity on display is striking, said Oliver Bown, author of Beyond the Creative Species: Making Machines That Make Art and Music.

“It’s able to coherently generate a multi-instrumental piece of music with metrical structure, musical phrases, progressions that make sense, all while doing it at a granular audio rate,” he said.

At the same time, AI mimicry has a ceiling of interest. Even diehard Beatles fans probably don’t listen much to “Daddy’s Car,” an AI-generated track from 2016 in the style of Sgt. Pepper’s. In these examples, the sonics can be replicated, but not the sense of innovation that defined the artists.

“Nirvana was famous for doing things in a different way than had come before, but machine learning is really good at doing things the way that humans have already done them before,” said Jason Palamara, assistant professor of music and arts technology at Indiana University-Purdue University Indianapolis.

While these kinds of AI tracks garner headlines, musicians are also using AI for composition in ways that resemble a collaborative, forward-thinking tool more than an imitation-game parlor trick with limited returns. 

“Nirvana was famous for doing things in a different way than had come before, but machine learning is really good at doing things the way that humans have already done them before.”

Writer Robin Sloan and musician Jesse Solomon Clark recently created an album using OpenAI’s Jukebox, which, like Magenta, can predictively continue a musical snippet. Holly Herndon’s 2019 album, Proto, described by Vulture as the “world’s first mainstream album made with AI,” incorporated a neural network that generated audio variations based on hours of vocal samples. 

“[Herndon is] working with AI as this sort of extended choir,” said Bown.

Inspired by these applications, artists and technologists hope for an even greater step forward. For experts like Palamara and Roger Dannenberg, a professor of computer science, art and music at Carnegie Mellon University, the holy grail of AI in music would be models that fruitfully collaborate with artists in real-time performances. Rather than edit down the interesting bits offered by a model that ingested reams of training data, humans could bounce off musical ideas with the AI, just like a bass player and drummer in a rhythm section.

Rudimentary versions exist, but with a host of shortcomings. A lack of sophisticated real-time musical interfaces means simple details for humans (like synchronizing and beat tracking) are a major challenge for models, Dannenberg said. The data limitations are pronounced, too. The Nirvana track stems from hours of rich MIDI data, but a live performance generates scant audio in comparison. So for live music generation, “you have to kind of dumb it down,” said Palamara.

Still, hope persists for a truly transformative AI accompanist in the not-too-distant future. “It’s a long shot, but it could have a huge impact,” Dannenberg said.

 

AI Music Examples

While advanced compositional AI remains the most interesting AI-in-music end game for many, artificial intelligence has already been impacting the music industry for years. AI-generated mindfulness ambient music, rights-free music generation for content creators and automation-assisted mixing and mastering have all matured into major industries in the last five or so years. And, of course, the recommendation systems pioneered in the music-streaming ecosystem have had major implications for all product recommendation engines

Here’s a closer look at some notable players.

Audio technology company iZotope emerged as a pioneer in AI-assisted music production back in 2016, with the release of Track Assistant. The mixing feature uses AI to generate custom effects settings based on the sonic palette of a given track. Today, it hosts a full suite of assistants that tailor starting-point suggestions for vocal mixes, reverb application and mastering. Because of its software and AI-centric products like Spire Studio, iZotope software has been used to mix and master records by artists such as Beyoncé, Kendrick Lamar and Foo Fighters.

Aiva Technologies is the creator of a soundtrack-producing artificial intelligence music engine. The platform enables composers and creators to make originals or upload their work to create new variations. Depending on the plan chosen, creators can also forgo the worry of licensing because the platform offers full usage rights. Rather than replacing musicians, Aiva wants to enhance the collaboration between artificial and organic creativity.

 

Founded: 2015

Location: New York, New York

Amper Music provides an AI music tool that performs, composes and produces custom music for media content. The web application enables creators to choose composition style, mood and length, crafting it to fit their content with no additional musical knowledge or skills. Amper was acquired by Shutterstock in 2020, but its Score program remains available as a browser-based tool and an API. It allows users to create a custom, AI-generated track in fewer than 10 clicks.
