The upright piano, when soft pedal, the hammers closer to the strings, so as to reduce momentum, reduce the length and intensity of combat, so that the volume becomes smaller. Its role is not only to help players play more weak, but also to increase the voice soft, and remove any percussion sound quality ingredients. Left pedal is often compared to "spin the music player's mute."
