Aliaksei Zholner specialises in creating cardboard models of steam engines and reed pipes among other examples. Now he’s created a fully functional paper piano, complete with a demonstration.

Sometimes you just have scratch your head and think, how? Aliaksei Zholner has come up with a micro masterpiece in the form of a paper piano. Plus, it works.

The video cleverly summarises the build from the frame of the piano, the “strings” (which are in fact thin strips of cardboard – and tuned, by the way!), the keyboard, complete with hammer action, and exterior soundboard. All this ingenuity is packed within a device that makes a toy piano look like a grand.

He tops it off by playing a few classic piano tunes, like Beethoven’s Für Elise and Scott Joplin’s The Entertainer.
