A piano produces sound through the striking of strings by hammers. When a key is pressed, a corresponding hammer hits the strings, causing them to vibrate. The vibrations create sound waves, which are amplified by the piano's wooden body. The pitch of the sound depends on the length, thickness, and tension of the strings.
The piano originated from the harp. Some guy decided to hit the strings with a little hammer and made a hammer for each of the strings. Now, when you hit a button, it strikes the string and makes a noise. A harpsichord was also invented like a piano except with plucking.

Piano keys are connected to levers which operate little hammers that strike wires (of different lengths) inside the piano. Organ keys are connected to valves that release air into tubes (also of different lengths). Electronic keys operate pre-programed sound synthesis mechanisms.
