Introduction to piano:

1. Piano (Italian: pianoforte) is a keyboard instrument in western classical music and has the reputation of "the king of musical instruments". It consists of 88 keys (52 white keys and 36 black keys) and a metal chord board. Italian Bartolomeo Christofi (1655- 173 1) invented the piano in 1709.

The range of 2.88-key piano is from A0(27.5Hz) to C8 (4 186.0 108 Hz), and the key 108 is as high as B8(7902. 13Hz), which covers almost all the tones in the music system except the organ. Piano is widely used in solo, ensemble and accompaniment performances.

3.Piano mbth is a piano, and its full name should be Pianoforte, which means weak and strong. Because this instrument can emit both weak and strong sounds, it has such an extremely vivid name.

4. Later, perhaps for the convenience of appellation, people omitted forte, meaning strong voice, and only retained piano, meaning weak voice, which has been used ever since.
