praecipito

   individual keys are released.    Let's take a look underneath the piano now.    Pressing the sustain pedal causes this rod to go up.    The rod pushes this lever up -    You can see this spring here keeps it pressed down most of the time.    The lever then causes another rod to get pushed up inside the piano;    this causes the Damper Lift Rail to rise,    which then raises all of the Dampers.    The sostenuto pedal is similar to the sustain pedal,    but it only raises the Dampers    for keys that are being played at that time.    Let me show you.    Play some keys,    press the sostenuto pedal,    and now release the keys.    You can see the Dampers for these keys are still up;    that's why we can still hear the sound.     Release the sostenuto pedal,    and the Dampers go down again.    Let's get a good look without the action assembly.    This bar here, is called the Sostenuto bar;    if I were to cut it in half,    this is what the cross-section would look like.    When the sostenuto pedal is pressed,    it will rotate like this.    On each individual Damper,    there's a tiny piece of felt sticking out.    So we play some keys, press the sostenuto pedal,    and when we release the keys    the Dampers catch on the bar.    Let's watch that again.    The mechanism is similar to what we've seen before.    When the pedal is pressed,    it raises this rod which pushes on another lever.    This time the lever is pinned in the middle.    As this side goes up the other side comes down,    which pulls this rod down from inside the piano.    This rod comes down, which rotates the bar and catches the Dampers.    Pretty neat, huh?    The soft pedal, as you might guess, well...    it makes the piano softer.   When you press it,    the whole keyboard is shifted to the right.     Let's take a look up here.    Normally, the hammer hits all three strings. digital piano under 1000    With the Damper pedal pressed,    the hammers are moved over just enough,    so they hit only two of the strings -    this gives each note a softer sound.    And now for the mechanism...    Pressing the soft pedal raises a rod and another lever.    You can see this lever is a bit longer;    it has a piece that goes up into the piano.    As the lever is lifted,    the end is shifted over just slightly;    this causes the entire action assembly    to move by just a touch.    It's just enough so the hammers miss a string.    Incredible music can be created    by playing the piano keys    in combination with the pedals, at just the right time.    Hey everyone, I'm Jared.    I'm the guy that makes these animations.    If you learn something about the piano,    I would love to hear about it in the comments.    Thanks again for watching and I'll see you next time.
