In the previous post, I showed the Amsterdam street organ. I mentioned that it was a bit like a player piano, and this video shows the punched “pages” that create the music. Also visible is the electric motor that now runs the machine. Originally, however, it would have been cranked by hand. So a lot more work in 1928 than it is now. Note that the costumed interpreter briefly covers her ears; the organ is surprisingly loud, and that appeared to be the reaction of everyone when it first started playing. But now you’ll know how it works.
