The Pedals         The purpose of a damper is to stop the vibrations of a string, and not every string requires one. Strings in the treble section release energy from their vibrations quicker which stops their sound in a small amount of time, so they usually don’t need a damper. While a player’s finger is pressed down on the key, the corresponding damper is lifted and the strings will vibrate freely. As soon as the key is released by the player, the damper will push back on the strings with vibration absorbing felt. Dampers can also be activated by the farthest right pedal below the keyboard. A player will press down on this pedal with their foot and this lifts all the dampers from the strings, sound will continue even after each key has been released. Musicians use this pedal to create a fuller and richer sound during their music pieces.                                         (screenshot from video) https://www.youtube.com/watch?v=fwqoHNhgbS8             To create a softer tone in their music, musicians will use the far left pedal, the “soft pedal”. By pressing down on the pedal, all the keys and hammers are shifted to the right. In doing so the hammers will strike fewer stings in each set of strings, for example on a grand piano only two strings of a set of three will be struck and only one string of a set of two will be struck. As for a vertical piano, pressing the soft pedal will move the hammers closer to the strings which decreases the momentum at which the strings are struck.         Newton’s first law of motion can be seen with dampers; an object will remain at rest, or in motion at a constant velocity unless acted on by a net external force. The strings of the piano will remain at rest until a player presses down on the keys. After the hammer strikes the strings and the keys are released by the player, and the strings will remain in motion (for some time) until they are dampened.
