The Piano - Musical Instruments .. The instruments we use every day and how they work

The Piano:

The piano is a stringed instrument, but it is a little different from the violin, guitar and other stringed instruments that we have previously studied. The first thing we notice is that the strings of the piano are not directly touched by the fingers of the person playing this instrument, but rather he strikes them - indirectly - by means of hammers (sledgehammers) covered with felt. Secondly: The strings of the piano cannot be lengthened or shortened to give different notes. Each string can produce a note with a specific pitch and not produce others.

In the normal piano there are eighty-eight notes, so you expect to find eighty-eight strings inside it. But in reality you find a much larger number than this number. The high-pitched strings are thinner than the low-pitched strings, and therefore they press on a smaller amount of air. Therefore, they are not very high. To compensate for this deficiency, there are three strings, all of which are high-pitched strings, and two medium-pitched strings, the first three strings. There is also one very thick string with a thicker tone of a low pitch.

1 - Each long string produces notes of a watt scale.
2 - Each medium-length string produces a medium-pitched note.
3 - Each short string produces a high-pitched note.

If you want to discover what is inside the piano, all you have to do is lift its cover and take a look at its strings. Here you will notice that the strings are of different lengths, and that the shortest of these strings are the highest-pitched (Rule No. 3). Then you will also notice that the low-pitched strings have a short high-pitched string wrapped around them to increase their weight and heaviness (Rule No. 4).

You will also see that each string has a small wooden block installed in it. These wooden blocks - which are called silencers - stop the vibration of the strings, after you remove your fingers from the keys. To illustrate this process, press a key and the muffler rises upwards, allowing the string to vibrate. Lift your finger from the key and you will see the muffler return to its place, preventing the string from vibrating. If it weren't for these wooden pieces that muffle the sound, the string you are striking would continue to vibrate for a few seconds, mixing the sounds it makes with those of the other strings you are playing. The result is that you get meaningless noise instead of music.
