The functions of the three pedals on the piano are as follows:
The functions of the three pedals on the bottom of the piano are sustain, silence and soft tone respectively.
1. The right pedal
It is also called the damper pedal, sustain pedal, forte pedal, and legato pedal. The principles and effects are the same on upright and grand pianos. When depressed, all the dampers that normally press on the strings immediately lift away from the keys, allowing all the strings to freely continue to vibrate. In this way, the sound played will continue to be prolonged until it naturally disappears.
When you lift your foot and release the pedal, all the dampers immediately press on the strings to stop the strings from vibrating, and the sound stops immediately. The right pedal can extend the sound, connect sounds with sounds, enhance the volume, and add color.
2. Middle pedal
On an upright piano, it is called the mute pedal. It lowers the thin velvet between the hammer and the strings to change the tone and volume. . The middle pedal on an upright piano is not used in normal music performance. It is mainly used to reduce the volume during practice without affecting others. There are also some upright pianos whose middle pedals are entirely manufactured using the principles of grand pianos.
The middle pedal on a grand piano is called a sustain pedal, a sustain pedal or a sustain pedal. If the player plays the next note or chord and presses the middle pedal at the same time, the note just played will be maintained, but the next note played by the player will not be maintained.
The middle pedal only opens the damper of the sound played when it is depressed, which is different from the fact that all dampers are opened after the right pedal is depressed. When the right pedal and the middle pedal are used at the same time, the middle pedal can retain some sounds, while the right pedal still performs its own tasks according to its own rules.
3. The left pedal
It is also called the weak pedal and the soft pedal. On an upright piano, when the left pedal is depressed, the distance between the hammer and the strings is shortened, thereby reducing the volume and changing the timbre.
On a grand piano, after the left pedal is depressed, the action moves to one side (the hammer and the entire keyboard will move laterally at the same time), so that the original three strings become two strings or A string vibrates to produce sound, thereby weakening the volume and changing the timbre. Depressing the left pedal is generally marked as una corda (the original meaning is one string), and releasing it is marked as tre corda (the original meaning is three strings).
Piano introduction:
The piano (Italian: pianoforte) is a keyboard instrument in Western classical music and is known as the "King of Instruments". It consists of 88 keys (52 white keys, 36 black keys) and a metal string soundboard. Italian Bartolomeo Christofori (1655-1731) invented the piano in 1709.
The range of the 88-key piano ranges from A0 (27.5Hz) to C8 (4186.01Hz), and the 108-key piano ranges up to B8 (7902.13Hz). It covers almost all the sounds in the music system, except for the pipe organ. The musical instrument with the widest range outside the world. The piano is commonly used for solo, ensemble, accompaniment and other performances.
