Una corda pedals, also known as the soft pedals, are piano pedals that allow the player to modify the instrument's sound by altering the way the hammers strike the strings. When engaged, the una corda pedals shift the entire piano action slightly to the right, making the hammers strike only two strings per note instead of the usual three. As a result, the sound produced is softer, mellow, and more ethereal in comparison to the standard tone.
The term "una corda" itself comes from Italian, meaning "one string." This reflects the fact that when depressed, the pedal causes the hammers to strike the single string closest to the player, instead of the usual middle and outer strings. This alteration in the hammer striking position produces a different timbre, with less volume and brighter harmonics.
Una corda pedals are typically found in grand pianos, positioned to the left of the sustain pedal. They can be engaged partially or fully, depending on the desired effect. Partial engagement allows for a slight change in tone, while complete engagement maximizes the softening effect.
These pedals offer pianists a versatile tool for expression, enabling them to create delicate and nuanced dynamics in their performances. They are commonly used in classical and contemporary piano music to evoke a softer, more intimate atmosphere. With the una corda pedals, pianists can explore new tonal possibilities and add depth to their interpretation of musical pieces.
