Keys are one of the parts of the piano that come into direct contact with our fingers when playing it. There are two kinds of piano keys, namely white keys and black keys. At first, the piano only had one kind of key, namely white keys. However, to make it easier for players to find out where certain notes are, black keys add between the white keys. The difference between white keys and black keys is their size and position.
The hammer is the part that transmits the pressure of the keys to vibrate the strings. The hammer is located just below the string. When pressing the keys, the hammer will hit the strings according to the location of the keys.
This part is what produces the tone at the time of pressing the button. The string will vibrate when struck by the hammer. The tone produced by the strings/strings depends on the length / short and thick/thin strings. The shorter and thinner, the higher the tone produced. On the other hand, the longer and thicker it is, the lower the pitch will be. The longest/lowest pitched string is on the far left, while the shortest/highest-pitched string is on the far right. Before it can be played, the piano strings must be tuned. Tuning on the piano is very difficult unlike tuning on the guitar. Because for one note, you have to use 3 strings (bass string, middle string, & treble string). Unlike guitar strings, piano strings are very strong and don’t break easily.
The damper is located above the strings and serves to adjust the length of the resulting string sound (sustain). The pedal moves the silencer, when pressing the keys, when the hammer hits the strings, the silencer will automatically lift/away from the strings but only temporarily. When no longer pressing the no key, the silencer automatically drops and attaches to the strings.
It is this part that actually produces the sound when the strings vibrate. The vibrations from the strings will be refracted by this board so that it can produce sound. Because actually, the soundboard on the piano is the same as the sound hole on the guitar. Without the earpiece, the guitar will not sound, likewise, without the soundboard the piano will not sound. The soundboard is located under the hammer.
Pedals are other parts that come into contact with parts of the human body when playing it, specifically the feet. Yes, the function of the pedals on the piano is for our feet. The purpose of this pedal is to give effects to the sound produced, such as making the sound last longer, making the sound instantly muted, and softening the sound. Most pianos have 3 pedals, but some have 2 pedals.
