Soundboard
The soundboard of the piano is the heart of the instrument. Soundboard amplifies and amplifies the vibrations from the strings. The wooden ribs, glued to the sound, help you make the sound throughout the piano production. To withstand downward pressure from the strings, the sound plate is bent into an arc that distributes the pressure throughout its shape.
Hammer
The piano hammers are connected to the action. When a key is pressed, the action pushes the hammer forward to strike the strings. Modern piano hammers are made of compressed felt that is thick. They are shaped like a balloon. The blanket is attached to a small wooden bar that moves the blanket forward on an upright piano and up on a grand piano, as the mechanism pulls the hammer back to allow the strings to vibrate.
Keys
A standard size piano has a total of 88 keys, 52 white and 36 black. The white keys have been assigned places — A to G. All black keys have two names because they are sharp or flat versions of the white keys. The black keys are arranged in two groups, the first set is a pair and the second set is a group of three. The first group is assigned the pitches C sharp / D flat and D sharp / E flat. The other groups ‘pitches’ are the following: F-sharp / G-flat, G-sharp / A-flat, A-sharp / B-flat.
Pedals
A standard piano has three pedals: damper pedal, pianissimo or soft pedal and mutation pedal. The damper pedal, when depressed, lifts the dampers, which prevent the vibrations of the strings, away from the strings. This gives a mixed sound, so that the note can continue long after the key has been pressed. The pianissimo pedal, depending on the piano type, either shifts all the hammers to the right (grand piano) so that smaller strings are hit at a time, or moves the hammers closer to the strings (upright piano), reducing the amount of space the hammer must strike the string, giving a softer tone. The third pedal, on an upright piano, places a piece of felt between the hammers and strings and on a grand piano, lifts the bass dampers, which helps maintain the specific notes.
Strings
The strings are part of the piano that vibrates, creates pitch and sou nd of piano. Each key can have up to three strings, which when struck, vibrate, creating a certain pitch. Each note, from top, farthest, farthest to the right, to the base, beginning in the middle to the left, has three strings per key. Depending on the manufacturer, the strings go down to two, then one for the lowest base notes. The strands are made of a hard steel wire attached to the pin pins, which are attached to the pin block at one end and a cast iron piece called the plate or metal frame. Bass strings are made of steel and packed with copper to increase their mass. The piano has hundreds of moving parts that can create the lilting melodies that are loved in the waltz or the incredible sounds of ragtime. Some of the parts that make the beloved melodies possible are the sound card, the hammers, the strings, the keys and the hammers. Modern pianos, unlike the first pianos, contain baffle frames instead of wood and plastic for the keys, instead of wood, which can carry down or warp or ivory, which is currently illegal.
