A piano is a simple machine. It is a lever. Every time you push a key of a piano, the lever will push that key down. Pianos are one of the musical instruments.
This is how the piano works. When a piano key is pressed, the back part of the key raised up and pushed the hammer attached to it. The hammer then strikes the strings and produces the sound of a note, and then quickly falls away from the strings so that it won’t stop the vibration of the strings. If the hammer doesn’t fall away, we would only hear a “clunk” sound, not a nice note.
Did you know that the piano has about 80 keys? Try it, I counted it myself. To me, making a piano is very, very hard. Back then, girls were attracted to play the piano. They thought that it was proper. Nowadays, there are many brands of pianos.
Who invented the piano? Bartolomeo Cristofori was the one! He made it for Ferdinando de Medici, who was the Prince of Florence.
