the threr lines on the hammer caused by the repeated striking on the strings does not affect the tone that much unless they're actually deep. These hammers don't require sandpapering.

Even thin string grooves have negative impact on tone. The impact is greater the further up the piano price/craftsmanship line you go.

Hi there iam wondering from size 1 to size 26 which size is considered to be a medium gauge piano wire?

@the_daily_ping 10 ай бұрын

Thanks for this. I just bought some B-72 and a hydrometer and this vide will really help me get started.

Does it need to be corrected often to maintain that octave shimmer? I’m guessing the octave string stops working as soon as that or any of the unisons drops in pitch?

@herrsitar 10 ай бұрын

Ah sorry this is one where they all have the same pitch. Tuned one yesterday where most of them were an octave up. Loved the rich sound but felt like it would not last very long no matter how stable the tuning since it needed to be so exact for the octave to resonate.

Piano wire that's 20+ gauge in diameter is where it gets more challenging..

The butterfly spring can be adjusted in the piano with a hart tool, thus raising the adjustable screw. No dismantling required.

For people who came here wondering whether or not the aliquot is tuned an octave higher or not: there was a different video where someone showed a very old Blüthner, which was different from the one in this video. TL;DR: If it's a modern Blüthner, same octave. If it's an older Blüthner, it's complicated. The one in this video has aliquot for the right most part of the piano, whilst the older Blüthner pianos also have aliquot that goes about somewhere in the middle part of the piano. The right most aliquots were tuned at the same level as the notes themselves, like in this video. The aliquots from the middle range were tuned one octave higher. You can find the video I'm referring to by searching "de-mystify bluthner's aliquot"

I just have not gotten around to redoing the video but if you get round nose pliers and some piano wire you will see very quickly how to make the bend...it's very apparent once you know what the end result should look like.

To my eye the teflon piece could be reduced in diameter so it would clear the spoon. Never encountered that problem on Schimmel's, 1986-1995

@EricJohnsonA 2 жыл бұрын

Trimming the teflon piece will address the symptom (catching on the spoon) but not the problem (weak repetition spring). I had never encountered it either...will only happen with a very weak rep spring and adjustment screw that has been screwed down too far. Any hertz spring whippen is susceptible to this.

Hello, greetings from Argentina!🤗 I'm having the same problem on a piano, what kind of product do you put on the hammers? is it an adhesive? Thank you so much!!

@EricJohnsonA 2 жыл бұрын

No adhesive! First choice is paraloid B72. See my video. 2nd choice is thinned lacquer that you get from hardware store. B72 is preferred if you can find it

I am so happy to find out this video, the rear/front duplex concepts are really interesting ! I have some questions, if you can please enlighten me: 1. If the harmonic effect that the duplexes create is important to the piano overall tone then why are there few piano manufacturers decide not to tune them ? As you said Steinway has untuned duplexes. Is it about the cost or something else ? 2. How do piano technician tune the duplexes ? Do they slide the metal pieces located near to the tuning/hitch pins at the both ends ? I am no piano technician, just a regular pianist but I found it SUPER interesting to learn how the piano operates. I just find it really cool of the piano technicians, who know everything inside the piano ^^. By the way, I am reading on your website, the video links lead me here. One more thing please 3. I read that the duplex scale only works at the capo area, which means from there to the bass notes, there are no tuning for the duplexes ? I just find it weird, why people mute the duplexes at the rear part of the middle & bass strings by a long felt rope. Thank you very much.

I don't understand what the glove is for. Could you also introduce heat as a catalyst to the dissolving process: sealed jar with crystals and alcohol placed in hot water?

@EricJohnsonA 3 жыл бұрын

The glove just suspends the B72 pellets in the solution to speed up the dissolving. Otherwise they end up in a clump on the bottom that needs to be frequently broken up and stirred around. I have no opinion on heating...maybe.

Thats not a duplex scale. The extra string length has been deadened by felt. That where you find the duplex if so equipped

@HelianGamePiano 2 жыл бұрын

May I ask, why do they make the extra string length deadened by felt ? I thought the extra strings vibrate, makes a richer tone, duplex scale or something ? Thank you if you response.

Yes, Randy is correct: this is NOT a duplex scale. For a proper example of one, simply google it, or look up here on KZbin.

What you mean 10 cents??

@EricJohnsonA 3 жыл бұрын

Hi Ryan. Piano technicians divide a 1/2 step into 100 equal parts, called cents. We use this because it is the same for every 1/2 step throughout the range of the piano, unlike using frequency (like hertz) which increase logarithmically and so is a different number for every 1/2 step. 10cents is 1/10 of a 1/2 step and, in the piano tuning world, quite a lot!.

Cool technique. I wish you had a before/after sound. No biggie. I have a set of hammers that need more. What Does this technique create? I've been thinking of experimenting with this. Guess it's time to try. Have you tried b72 yet with same technique? Lots of questions. Thanks for putting this video out. I would suggest using a acid brush to do this. Its very exacting.

Does aftertouch make a big difference in sound vs not having it?

@EricJohnsonA 4 жыл бұрын

Well...yes, but not necessarily as a separate regulation. It's kind of complicated...it makes a BIG difference to the player so too much or too little aftertouch really affects the way the player manipulates the key and therefore the tone. But just regulating aftertouch a little does not necessarily have an impact.

@TubeOzaurus 2 жыл бұрын

So it means that AFTERTOUCH influences the sound/tone INDIRECTLY by affecting the playing of the pianist via mechanical feedback?

Love the video! (And love those Ronsen Weickert felt hammers!) I was lucky to obtain a hardening protocol from the Ronsen co. written by their friend and technician-extraordinaire Dale Erwin. Interesting thoughts to combine with one's own. I'm sure they'd be happy to send to you (if you don't already have it).
