2026 Fellow

For the invention of audio FM synthesis, which transformed the musical landscape using computers

I was aware that I was probably the first person to ever hear these sounds, and that what I was hearing was something musical that had probably never been heard by anyone before—at least, not by anyone on this planet.

John Chowning is an American composer and researcher whose 1967 discovery of digital frequency modulation (FM) synthesis was a major intersection of computer science and human artistic expression. While at Stanford University, Chowning recognized that certain mathematical relationships between electronic oscillators could create rich, complex timbres using remarkably little computational power. In an era where digital memory was a precious commodity, his efficient algorithm was revolutionary. By turning complex equations into vibrant, organic sound for digital instruments, Chowning moved electronic music from the periphery into the mainstream.

Chowning’s breakthrough redefined the global music landscape. Stanford’s licensing of the FM synthesis technique to Yamaha birthed the 1983 DX7, the first commercially successful digital synthesizer. Chowning’s technique effectively defined the sound of the 1980s and ’90s. In 1986, 40% of all the Billboard Hot 100 songs for that year used the DX7 by artists such as Phil Collins, Whitney Houston, and U2. By the turn of the decade, his algorithm had moved beyond high-end studio synthesizers and into mass-market PC sound cards such as the popular Sound Blaster card, which used Yamaha’s FM chips to define the sounds of early ’90s PC gaming.

Based on the FM patent’s success, Chowning founded the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford, providing a creative home for generations of digital artists and creating one of the world’s premier computer music research centers. His work demonstrates how pure research can drive industrial innovation, and that computing is not only about processing data but also about expanding the limits of human experience.
