The structure of the piano: The piano is composed of 88 keys (52 white keys, 36 black keys) and a metal string soundboard.

The principle of the piano: The predecessor of the piano is the harpsichord, also known as the harpsichord. It has roughly the same internal principle as a piano, with a soundboard and many strings that are tightened and tied inside the body. The difference is that the hammers of the piano strike the strings to produce sounds, while the harpsichord uses the plectrum of the quill to produce the sounds.

In addition, there is a keyboard instrument with the same origin as them - the clavichord, which is also an instrument equipped with a string striking device, using a copper-shaped mallet to strike the strings to produce sounds; The range of applications is not as wide as that of the harpsichord, and it was mainly played in aristocratic families at that time.
