A piano pedal is a lever located at the base of a piano that the player can press with their foot to modify the sound produced by the instrument. Most pianos have three pedals: the right pedal, known as the sustain pedal, allows notes to ring out longer; the left pedal, called the una corda, softens the sound; and the middle pedal, often referred to as the sostenuto pedal, sustains only the notes that are being held down when it is pressed. Using the pedals effectively can enhance a pianist's performance by adding depth and expression to the music. The sustain pedal is particularly important in creating a smooth, connected sound, while the una corda pedal can create a more delicate tone. Understanding how to use these pedals is essential for achieving a professional sound on the piano.
