Oldest Computer Music Unveiled
drewmoney writes with a cool story from the BBC, which says that "A scratchy recording of Baa Baa Black Sheep and a truncated version of In the Mood are thought to be the oldest known recordings of computer generated music. The article also collects some other very interesting bits of computer history.
It reminds me of an album called IBM 1401, A User's Manual by Jóhann Jóhannsson. It is simple computer music generated 30 years ago that has been orchestrated.

My father remembers as a schoolboy around then visiting the laboratory at Manchester, and asking how it made noises. IIRC he says they were actively loading the system clock and making it slow down or speed up depending on how much work it was doing driving circuit elements.
The nice thing about it though was it served as an excellent diagnostic aid. When the full system was working properly it would make a very complex sound, a bit like a dishwasher or something, but when it hit a bug and hung you'd get a single tone (a bit like those "beep beep beeeeeeep" monitors in hospitals). And you could tell when things were starting to go wrong, a bit like listening to a car engine. Quite cool, I sometimes miss being able to "listen" to complex programs executing.
... that it was Christopher Strachey who wrote the music programs? That's the guy who invented CPL and he was also involved with BCPL, the ancestor of C. He wrote the book "BCPL - The Language and Its Compiler" together with Martin Richards. That book was my introduction into compiler design! :-)
