Piano accessories:

1, pedal

Pedal refers to the pedal under the piano. It is the most important accessory in the piano except the keyboard. It was invented by Italian musical instrument manufacturer Christopher Foley in 17 1 1 when he reformed the piano.

2. Hammer

The hammer is covered with high-quality felt or flannel. Because this "skin" is mostly made of wool, it is also called wool hammer. It is attached to the key. When the keys are pressed, the hammer will knock off the strings and make the piano sound through the vibration of the strings.

3. Sound board

The soundboard is located on a big wooden board inside the piano. Maple solid board for high-grade piano and density board for modern low-end piano.

It is attached to the tuning nail and clings to the strings. When the strings vibrate, the soundboard will efficiently couple sound waves into the air, that is, the sound will be reflected and amplified through the soundboard.
