The sustain pedal is a vital part of a piano or keyboard. It is an essential tool that allows the player to sustain notes for a more extended period. In the music industry, the pedal is widely known as the "damper pedal." However, it goes by other names depending on where you are in the world. In some countries, people refer to it as the "sostenuto pedal," while in others, it's known as the "una corda pedal." Some also call it the "soft pedal" or the "loud pedal." Regardless of the name, the sustain pedal remains a must-have accessory for any pianist or keyboardist.
