On Saturday, Ludwig van Beethoven鈥檚 new symphony will premiere in Bonn, Germany. Technically speaking, the German composer鈥檚 10th Symphony is a co-write. His collaborator? A computer.聽
Beethoven left behind fragmentary sketches for the follow-up to Symphony No. 9. Almost 200 years later, 聽have taught artificial intelligence how to predict which notes Beethoven might have chosen for the missing pieces.聽
鈥淲hen you write your email or text, your [computer] or phone suggests to you what words you would write next,鈥 says team member Ahmed Elgammal, director of the Art & AI Lab at Rutgers University in New Brunswick, New Jersey. 鈥淭his kind of predictive model is very similar.鈥
The 18-month project was an iterative process. Computer programs learned to recognize patterns in Beethoven鈥檚 creative process by examining his earlier symphonies. The AI also had to figure out which instruments to use for the arrangement, which will be performed by the Beethoven Orchestra Bonn.聽
Mr. Elgammal happily offers a preview by humming a few bars of the 25-minute piece. (Schroeder, the Peanuts pianist, will finally have something new to play by his hero.) The programmer knows that critics will question whether computers can replicate Beethoven鈥檚 genius. Yet he believes there鈥檚 plenty of joy in this ode to the beloved composer.
鈥淚t鈥檚 basically a way to show the world what AI can do,鈥 says Mr. Elgammal, who believes it鈥檚 a tool akin to a creative assistant. 鈥淚t has a major role in the way art will be created in the future.鈥
