How do pianos work?
Behind every piano’s polished exterior are thousands of parts. From keys to strings, they work together to produce a sound. In this episode, we take a field trip to a piano shop, peek behind the walls at a world-famous piano factory and have an EPIC FIGHTING BATTLE to discover how sound travels.A piano may seem simple — 88 black and white keys that you just press with your fingers. But what you might not know is that each time you press a key you’re engaging a complicated machine. There are thousands of parts inside every piano.
When you press a key, a felt-covered hammer inside the piano strikes metal strings. It is the vibration of these metal strings that make that familiar piano sound. But the most complicated part is the action, a Rube Goldberg-looking series of parts and levers that work together to make the hammer strike the strings.
