For the benefit of those who don't know, player pianos are self-playing pianos. These machines have been around since the 1890s and this example, now preserved at Dingles Fairground Village, was constructed in about the 1920s. How do they work? - You may ask. To start with, some of these would either work by electricity or air (like the one in the photo). In further detail, the mechanism inside the piano would suck air through the perforated paper roll before travelling into a set of bellows which, in turn, play the keys (the mechanism, on the whole, is, on this particular player piano, driven by a pair of pedals).
