This is an educational film from 1983 describing a little bit of the history and tools of electronic music. The best thing about it is that it is behind the times for 1983, and seems more like a 1970s film. Frequently featured is a Moog modular! Also featured is a Fairlight, but as an analog obsessive, I’m less interested in that.
This reminds me of the old Encyclopedia Britannica films we watched back in high school. Despite being quite vintage, the content of the film is still relevant today.
