Beethoven or Bot? – Evaluating an AI’s Completion of Beethoven’s Tenth Symphony

Beethoven or Bot? – Evaluating an AI’s Completion of Beethoven’s Tenth Symphony

Although most of the hubbub surrounding Beethoven’s 250th birthday has subsided, a few bits of the celebration have lingered into 2021 as concert halls worldwide open up once again. However, one recent Beethoven item has raised many eyebrows in the music world. Back in September, the news broke that a team of computer specialists and music scholars had “completed” Beethoven’s unfinished Tenth Symphony using AI technology and scant scraps that Beethoven left behind upon his death in 1827. Dubbed “Beethoven X: The AI Project,” it was also announced that recording of the results—played by a live orchestra—would be released the following month. Like many, I was skeptical. This just seemed like another lame excuse for more Beethoven deification, one that would take the focus away from issues that are currently more pressing, like promoting diversity and equity in classical music.

Still, I was curious what the results would sound like. So, I recently met over Zoom with my friend Tanner Cassidy—a PhD candidate in music theory at UC Santa Barbara—to listen to it and share our impressions. (There may have been a smidge of alcohol involved as well… *wink*) Below are excerpts from our discussion, which have been edited for length and clarity. What did we think? Does a computer have the potential to live up to Beethoven or is this something best left in the trash bin? Let’s find out…


Kevin McBrien (KM): So about a year or two ago, this German telecommunications company [Telekom]—with AI specialists and music scholars—was like, “Hey, let’s take these incomplete sketches of Beethoven’s Tenth Symphony and feed it into an AI program and see what happens.” And this is the resulting piece that came out of it. There was this musicologist—Barry Cooper—who reconstructed the first movement in the 80s and that’s been recorded and released as kind of a hypothetical Beethoven 10. And this one, apparently, is just the third and fourth movements.

The musicologist Barry Cooper realized the first movement of Beethoven’s Tenth in the 80s, which was subsequently recorded by the London Symphony Orchestra.

Tanner Cassidy (TC): So there’s no second movement that exists?

KM: I guess not, or there’s not enough to go off of.

TC: I actually have some experience with AI-generated music. An undergrad friend of mine was writing bebop-based algorithmic composition, where he fed it Charlie Parker licks, and then he had me play what the computer spit out, which was just nonsense. AI has really struggled with rhythm, so I’m really curious to see what rhythm sounds like.

KM: Yeah, I heard a snippet of it on an NPR story, and it’s weird. So, I’m also curious to listen to the whole thing.

TC: Well, I’ll mute my audio, and then we can listen to this.


[We listen to the third movement.]
