(Music Playing)
Male1: But, like I said stand by those on results. Okay, here is the action coming out, lovely. Now, here we go. No, if you do this at home please be sure you do not push any keys down when you pull action up because you will break on cameras, you will get caught on the other side of the edge of the ten block I have snap also ago. And you will match your teeth and do not blame me. Now, it is pretty easiest for the CDN. Now , this a very high evolve device. Probably the most complex mechanism. It mostly composed of wood. Now, it quite mysterious for most people. So, as you press the key. Now, the key is just simple leader. Okay, it is got a central bouncing point. Now, that also functions as a guide pin and there is also a guide pin at the front as the key goes down that engages this item here called the weapon. Well, this actually the Jack tender or tail. But, that is the part of weapon assembly. So, if you just press the key that pushes up the weapon and this is called a roller or it used to be called a knuckle. This field use to taught me, use to do that. Now, this little item here, this little pig, that cause of it is called the jack. That was actually pushes the hammer up. Now, without the hammer in place you will see that there is whipping comes up this is called the repetition leaver here as the whipping rises, the jack maintains each position until it engages a button called the regulating button.
Male2: Where is that?
Male1: It was right there.
Male2: Alright there, okay.
Male1: And is not that catches the jack tender and causes the jack to move away from.
Male2: It was little roll about that off and that is extremely extending.
Male1: Yes, the whipping moves of the jack is propelling this forward, upward I should say before in a vertical piano and then at the certain point the jack kicks out from underneath.
Male2: As it escapes out of there.
Male1: It does the escaping, yes. Otherwise what we happen if you have this regulating button set to high then the hammer which is block against the string.
Male2: And that is like going good that is a piano.
Male1: Yes, it did very peculiar thing that he would do that the amount of control he must have would be amazing. I can hardly imagine. Sorry not show that is all how it grand action function now up to the hammer hits the string which should be serious string about one of seven inch higher then the hammer is the rest expedition and then it is level over the extreme position. It would be very close to the hammer as it lefts off that it could gives you a maximum.
Male2: And I am just dropped back off.
Male1: No, when the jack kicks out the hammer comes back out on the repetition leaver. And it is only allowed to flow so far and then when you let up in the key if this thing is regulate correctly. If you let up the key a little bit and up the hammer goes and that allows the jack to get back underneath again. So, that you can play a very, very rapidly repetition.
Male2: I know they do not have the same quite quality on that upright so there is the gear is on.
Male1: If they will regulate and then it is a good pulse eye action. The repetition on upright really leaves a very little bizarre and for most purpose is really just one fast enough.
(Piano Demo)
You know when I finish tuning an upright piano and regulating it, I can use the guitar, kind of repetition.
(Piano Demo)
So if you could take a period think of that stuff repetition but really I am only playing each key about that fast.
(Piano Demo)
You can actually get that twice that fast thing.
(Piano Demo)
Male2: Yes.
Male1: But, it is very, very pieces I could think of some tridents where he is playing. A repeated it was like a key of that note.
(Piano Demo)
Male2: Yes.
Male1: I leave in the sky light to a astronomy sonata.
Male2: Let us in engage on rhapsody to have in the middle of section days, last repeated section there.
Male1: Yes, because his trying to seminate the hammer doors mere on in which is they call it timbalong in Hungary I believed. And they played its little hammers. It is almost like of combination of percussion technique and keyboard technique.
