Alan Turing: Listen to Restored Recording of Music on his Turing Machine

Alan Turing is best-known as one of the world’s first computer scientists and the brains behind the effort to crack the German’s Enigma code during World War II, but his career didn’t end with the war. Not only did he continue to make strides in designing early computers, but he was also one of the first people to see their potential as musical instruments. Now, a group of researchers have uncovered and restored one of the earliest recordings made on Turing’s early synthesizer.

While working at the Computing Machine Laboratory in Manchester, England during the late 1940s, Turing figured out that he could make his enormous early computer produce identifiable musical notes by programming the CPU to play a clicking at certain intervals as it spun, Steve Dent reports for Engadget.

These sounds were a far cry from anything 1970s synthesizer pioneer Robert Moog would create decades later, much less anything in modern electronic music. In fact, it wasn’t even really electronic music, as the notes were created by moving parts inside the computer. But the fact that Turing figured out that he could program the computer to create these tones was remarkable, the Agence France-Presse (AFP) reports.

At the time, Turing wasn’t interested in having his machines make music. But when a budding programmer and musician named Christopher Strachey got his hands on the manual for Turing’s Manchester Mark II computer, he used this trait to program the machine to play “God Save the Queen,” Dent reports. At the time, it was the longest computer program ever written. A few years later, Turing put on a demonstration for the BBC, which recorded the computer playing a total of three songs [God Save The Queen, BaaBaa Black Sheep and Glen Miller’s In The Mood] on a 12-inch  single-sided acetate record.
