How a piano makes a sound when you press a key down

Have you ever heard a piano playing in the background of a song on the radio or seen someone play the instrument? Has that ever lead you to wonder how that sound of the piano was made? A piano has a lot more of engineering on the inside than the glossy appearance you see on the outside. A piano has a wooden key that extends all the way into the inside of the piano. When you push any key on the piano, the other end of the lever goes up and the hammer attached to the piano hits the strings for each key. The damper makes sure that the string does not continue to vibrate so when the lever comes back down (when you take your finger off a key) the damper goes and rests on the string on the note.

Here is an article for a more detailed description on how a piano makes sounds and more:

This relates to engineering because Bartolomeo Cristofori and many other people engineered and designed different models and versions of the piano. A single piano goes through a lot of construction and detailed thinking to ensure that the piano will make sounds. To be able to use or play a piano you need to use your brain and think about the way that you can impact the sounds of each note. It can take over a year to build a piano, starting with shaping the wooden frame under a press instead of using water or steam to bend the wood. When a piano is finished, it goes from one engineering project to the next engineer who can create and play beautiful pieces on this instrument.
