What is the purpose of the damper pedal on the piano?

The primary purpose of the damper pedal on the piano is to sustain notes. When you press the damper pedal, it lifts the dampers off the strings, allowing them to vibrate freely even after the keys are released. This results in a sustained sound that can enhance the singing quality of the music being played. The effect produced by the damper pedal creates a more connected and legato sound, which is particularly important in expressive playing.

Sustaining notes with the damper pedal enriches the harmonic texture and allows for longer musical phrases without interruption. This capability is essential for interpreting many styles of music, where sustained chords or melodies enhance emotional expression.
