In 1957, Max Mathews, an acoustic researcher at Bell Telephone Laboratories in Murray Hill, New Jersey, wrote Music I and used it to generate the first examples of digital audio. During the next years, he finished Music II, Music III, and Music IV.

In 1964, Jean-Claude Risset arrived at Bell Labs and used Music IV to digitize the sound of a trumpet. It was the first successful digital reproduction of a brass instrument. It also marked the beginning of acoustic research linked to digital synthesis. Max Mathews, Joan Miller, and others produced, among other things, a computer voice singing 'Bicycle Built for Two'.
