No human producer? No problem

Algorithm alchemy: Taryn Southern used artificial intelligence to produce her album
Algorithm alchemy: Taryn Southern used artificial intelligence to produce her album, after struggling to compose music herself because she didn’t know how to play any musical instruments

They may never be able to fill a stadium for a rock concert, but computers are making inroads into the music industry and are capable of producing songs —convincingly so — as illustrated at the South by Southwest (SXSW) festival in Texas.

Already, an album featuring eight tracks has been produced entirely with artificial intelligence (AI), an unprecedented feat.

I Am AI was released in September last year by YouTube star Taryn Southern, who doesn’t know how to play any instruments.

“For my first music video in 2017, I had a lot of friction as a non-musician,” Southern told a SXSW panel discussion on Sunday at the festival, which is running from March 8 to 17. “I wrote lyrics, I had a melodic line but it was difficult to compose and record the actual music.”

The pop artist said she began experimenting with AI two years ago, working with Amper, an artificial intelligence music composition software.

“In two days, I had composed a song that I could actually feel was mine,” Southern said. “It means that I don’t necessarily have to rely on other people.”

Founded in 2014 in New York by a group of engineers and musicians, Amper is part of about a dozen start-ups using artificial intelligence to break with the traditional way of making music.

The company’s cofounder and chief executive, Drew Silverstein, said the aim is not to replace human composers but rather to work with them to reach their goal.

He said the company relies on tons of source material — from dance hits to classical music — to produce custom songs.

“The idea of Amper is to enable everyone to express themselves through music regardless of their background and skills,” Silverstein said.

The Amper app allows a user to pick a genre of music (rap, folk, rock) and a mood (happy, sad, driving) before spitting out a song. The user can then change the tempo, add instruments or switch them out until the result is satisfactory.

Two songs created by Amper at the SXSW festival, using the public’s choice of pop and hip-hop as the genres and tender or sad for the mood, aren’t likely to top the charts. But the pieces were pleasant to the ear and perfectly usable as background music to illustrate a video or a computer game. Such songs are described by Amper as “functional music” as opposed to “artistic music”.

Southern said she reworked the music on her own album dozens of times before she got the right tune.

“For me, it’s just a tool I can use in my creative process: I’m still the editor, I’m still in the driver’s seat,” she said.

She acknowledged, however, being terrified her album would be panned when it came out, as was the case with other innovations in music, such as synthesizers or software to help artists to sing better.

Jay Boisseau, a computing technologies leader and strategist, predicted that more and more music will be generated by computers in the future, but the machine was unlikely to totally replace the human touch.

“We’re going to hear a lot of music composed by computers and there’s nothing wrong with that,” he said. “But computers are not very good at creativity … they are 0 and 1.

“They can find patterns, but they’re not, like humans, particularly good to go beyond what they’ve been trained for. They are tools.”

For Lance Weiler, an American filmmaker and writer who uses AI in his work, the collaboration between machine and artist should not be sneered at.

“It mainly enables you to improve the way you work, to augment your skills in expressing creative thoughts,” he told the panel discussion.

There was no question that AI had its limits and inevitably fails somewhere, he added.

“It’s like interacting with a toddler,” he joked. “It can be very temperamental. You need to put patterns so it doesn’t hurt itself.”

Silverstein underlined that, although AI was useful to experiment with an objective goal — “a yes or no answer” in terms of artistic experimentation — it was far from perfect.

For some, such arguments are not convincing, as attested by a British musician at SXSW who didn’t appear happy with the competition and questioned whether the word creativity even applied when speaking about music generated by a computer.

“It’s still an algorithm,” Boisseau conceded. “It’s doesn’t mean people won’t enjoy it, but it’s not completely new.

“With the current state of the art, it cannot be ‘creative’,” he added.

To which Silverstein quickly replied: “Not yet.” — AFP
