Occurred when a key is pressed on an acoustic piano, the resulting sound is for a considerable time after pressing a button and stops when the button is released and allowed them to grow. This elimination of the sound is caused by the action of a second piece of piano mechanism, the so-called shock. The dampers are small pieces of wood with felt connected to them.
This mechanism is associated with that key, that this is a movement without movementshock really. Each key is thus the means by which both a hammer and a cushion to be moved to action, the hammer for the production of sound, the shock is to stop. (In the case of some of the keys on the piano, the damper mechanism is missing.)
The damper is in constant contact with the string, except during the repression of the key when he removed from his post and kept the curtains, while the button is held down. After a pushdown automaton is the key when the key is kept low,Note that (1) removed the hammer is based on its position half-time and (2) of the damper from the string. If the key is allowed to rise, the hammer falls completely, and the flap again to touch the cable, and through him, the sound stops.
If there was no provision for the cessation of sound, the effect of power is the same that would be produced when the right foot pedal is held down during the game. The suppression of the pedal caused the elimination of all the shock fromStrings, and the creation of about the effect of each sound in all the others.
If the hammer was stressed that the complete work as quickly as possible, which ends once it is made, and that even if the button is held down (and thus can be understood to have a function to be) designed, or does not need to be expected from a hammer.
Please note that the two mechanisms depends on its keynamely, that it is for the production of clay, and this arrest. As long as the button is pressed, is part of his work when the key is allowed to change is increasing, and hears the sound.
It 'been shown that the job is the hammer at the time of the race completed. And 'so the work of the damper, the suppression of the key is an important tool in promoting. What the hammer work as soon as you press the button over contrastthe work of the damper is closed until dawn key. The work of the damper is to stop the sound, and how the block can not occur until the cord comes through the door, do not touch can be as long as the button is touched again, the work of the damper is then is not ready until the key is to get permits.
The positive impact of the hammer occurs when the button is pressed. The positive effect of the shock occurs when the button is released and allowed them to grow.The negative effect of both hammer and damper, namely the freedom to leave the string to vibrate after the stroke. Thus, while both the hammer and the damper begin their work at the same time, complete at different times, the hammer once, and the flap is not up to the tool button is allowed to rise.
All work completed between the hammer and the completion of the work is the work done as a shock absorber of the soundboard of the piano, but asthis work is all about interim control of the finger, can not in any reflection on how to touch the keys.
