How A Piano Works and Makes Sound
How A Piano Works & Makes Sound
When a piano key is pressed, a hammer flies out and hits a string tuned to the corresponding note. The mechanical effect that enables the hammer to immediately detach itself from the string is called inhibition. When the piano keys are pressed, the hammers fly out, strike the strings tuned to produce a corresponding note, and then fall on another string if they do not stop their vibration. When the hammers stayed in contact with the strings, they produced a sustained sound. It is important that a piano has a damper so that its strings can be kept calm. If the piano is played in such a way that the felt compresses extremely tightly around the striking string, it creates an unpleasant, rough sound in the sound system. If the damper is not present, the piano cannot repeat the sound produced by contact with it.
The Vibrating Strings
When you press the "sustainable" or "damper" pedal of a piano and sing the same note, all the strings on your piano vibrate, making the sound you are singing vibrate. When the vibration of one object causes another object to vibrate, it is called resonance, and this is one of the most common types of sound effects. The vibrations of piano strings alone would be too quiet to be heard, so their sound must be amplified. Piano strings, like violins and guitars, are pressed into a bridge that conducts their vibrations through a large, thin piece of wood called a soundboard. Wooden ribs glued to the underlying board help to distribute the string vibrations over the mass. The vibrations of the strings are transmitted to the soundboard via a bridge through which the string is stretched, and the hammer mechanism composes the action. The hammer that hits the ring is attached to a mechanism that rests at the other end of each key.
A Piano's Soundboards
A hammer on the mechanism consists of two pieces of wood, one above and one below, of the same shape and form as the soundboard of the piano. Each of these soundboards affects the sound and quality, but not in exactly the same way as a piano string. Early pianos had wooden frames and could therefore only be strung lightly, but modern pianos have cast iron frames that can withstand enormous tension on the strings. The piano uses each key to move the hammer that hits the string inside to produce the sound. In the late 18th century pianos were played by Mozart, Bach and other great composers such as Johann Wolfgang von Goethe and Johann Sebastian Bach. In a piano, the strings are not plucked with quill, but struck with a block of wood, the so-called hammer, and covered with felt. In the late 18th century a clavichord was developed that looks like a piano, but with small metal blades, the tangents, meets the string of the clan. On a grand piano, each string is struck and struck by a felt hammer. When the performer gently presses a piano key, the strings are struck with a hammer, creating a gentle sound. But when he pushes hard on the key and strikes hard, each string is also struck with a hammer, which leads to a loud noise, and when he pushes gently on the piano keys, both strings hit the hammers. The only variable that ultimately determines the sound is the speed with which the hammer hits each string, and that determines how strongly the strings vibrate.
The Hammer and Variation
He presses his fingers on a lever on the key, which then throws the hammers on the string. The lever disconnects from the hammer, so that the ring continues to vibrate while holding on to the keys. Likewise, the overtones of the piano strings are determined by how hard the hammer hits each string. The piano contains hammers that hit the metal strings, making it in this category. When the strings vibrate, they produce a sound just like a violin bow, a guitar plucks, or a piano makes an effort. The keys and strings are paired with a distinctive instrument, the clavichord, which led directly to the invention of the fortepiano and fortepiano. Sometimes keyboard instruments such as the organ, harpsichords and clarinets are classified as keyboard or organ. The Cristofori piano has a method in which the hammer hits the strings and then falls back and strikes again and again while moving the action parts connected with the keys. This method allows the string to continue vibrating and sounding instead of being struck loudly or quietly as on a harpsichord. The hammer is caught by the back of the check - hammer - check so that it bounces up and down on each string after the first blow. In 1709 the Italian harpsichord maker Bartolomeo Cristofori replaced the plucked pegs of harpsichord sounds with a small leather hammer to strike the strings.
