Quote from: Maui on November 27, 2004, 12:25:55 AMThe middle pedal in Grands is called "Sostenuto" and it's a soft damper.On most pianos nowadays, the middle pedal sustains those notes that are pressed when the pedal is pressed, but not the following ones. Example: play a note, hold it, press the middle pedal, release the note, play more notes. You will notice that the dampers of the first note will stay off until you release the pedal, but the following notes are not affected.However, the function of the middle pedal can vary between pianos. Simply "playing around" should reveal it.
