Piano World Home Page Forums Our Most Popular Forums Piano Tuner-Technicians Forum Dan Levitan's Lever

I discovered this the other day. I've found mention of this very lever in various discussions, but have never seen one in action. So, for those who are interested:

My tuner uses one of those. Perhaps not so surprising since he has the same name as that guy on the video.

Dan is a pretty amazing composer also:

It's a well made tool. I have tried it and it is based on a principle that I used in making a different tuning lever about 30 years ago. It's physics and the principle is definitely valid.

Interesting lever, cool for the body indeed.
However if it falls it may cause some trouble with the customer.

Dan Levitan seem to like the tuning methods that lighten the pressure of the string on the front part of the hole , the weight of the lever is really at the opposite of the string

I did not analyze close enough the first part but the pin seem to be cracking a lot

That is some lever.

Interesting lever! Does anybody know the list price in the US?

there is a web site..

His tuning technique seem to be coherent,(changed from the unisons demo video where it was PR quality) .

But still he act a a "piano tuner" that does not listen to the piano, does not build tone, only focus on partial beats, pitches, and anaesthetized tone (no life) (find if a string is too sharp or flat by playing a M3 is a sign, listening late another, not lively playing hand the last).

I'd like to try that lever, but need to know the weight first.

You can notice he correctly use twisting and bending for equalizing pin tension. As he does not seem to use it by slow pull the pin is somewhat separated from the string (as an element ) The huge advantage of slow pull is that it makes you consider the pin and the wire the same (I tell about the tactile thing)

This is very useful to know how much stress you have left; if you do that by very small cracks or nudges only experience let you know where you are... (you are obliged to trust the piano)

I am not criticizing the tuning or the method, BTW, I just see that while at the same time the quality is very professional, it can be very little different and then more lively.

Sparing regimen for the pin - yes. But the feeling hand of the tuner to change the sound when you set up will be much harder. You can make a 4 foot crank for the C-bar, but tuner will work much longer than usually

I gotta say, I don't get you.

Kamin, I believe he was only showing a demonstration of how the lever is used in various parts of the keyboard. Ergonomics and clearance of cabinet parts was the focus....not an aural tuning demonstration, per se.

The design of it makes sense, as far as lowering the plane of applied force to where the pin is, not above it. However, the advantage of not leaning out over the grand seems to be the opposite effect, on an upright. The upright tuning position looks more strained, having to reach out farther then conventional levers would have us do. I would have to try one to confirm this, since it just may be a matter of adjusting to the new position and things balance out.

A rubber sleave over the whole unit may prevent dinging up the cabinet moving it around, should it happen to slip off a pin, or if one is a bit careless with it.

Yes the demonstration is well done and complete, however I see may be more flagpoling than I would like, and I question how you get a good feel for the pin rotational plane with this setup.
Each time he moves the lever I see the pin going front or back, may be just a visual effect from the video, but I try to stick to the rotational plane more than that. Also I hear the pin cracking both directions, that mean it is worked with some torque pushing on its bed.

Sure about tuning unisons it was not the purpose but I see no reason why he should do differently. He tune just a little too soft and late, not working the tone during the attack.

It is very possible that the kind of voicing of the US pianos does not propose more projection if you work the attack of the tone (when the note speaks, not a second later) as it seem to me that the attack is often not very concentrated, I have problems to describe that, the attack often seem to provide the same tone quality than after, it is not the case on european pianos, where the attack can be more hard while allowing for a lively projection of toneimmediately after the initial "crack"

SO we tune very soon in the tone, for the projection and fast coupling, but still not exactly at the attack (there are different possibilities, I see that as regulated in regard of the moment the key is at its bottom and the hammer is rebounding on the strings - so depending of the touch you use when tuning you will have a different type of tone.

Tuning late provide the most part of the job, but if one begin to tune sooner you can work more on the energy usage : more for the attack or more for the sustain, and so you adapt your touch to the piano you are tuning.

The pianist have to feel the energy of the attack under his fingers, the best way to obtain that is to tune that moment of tone too.
If not you can have a perfectly tuned piano, even with a nice tone, open, clear, strong, for the audience, but something is missing for the pianist (in fact for the audience too the tone is not going around the instrument as much, it can tend to go straight to the ceiling, or just not fulfill the room as much as with a rich attack.

Indeed it is not certain that the attack is not worked when Dan is tuning ,(as long as you have the good sensation in your playing hand you are aware of the attack gestion, even when playing softly, but then you play softly but still firmly)

I see him not putting much energy to the string, hence my conclusion.

I'd like to know the weigh of that lever, the lenght is certainly not a problem, but above a certain weight it is may be less easy to decide how much torque is left (he states correctly the level of torque and bend to be left in the pin)

It appears from searching the web that the Levitan tuning lever can only be obtained from PianoTek which in turn will not sell to non piano technicians. Is there any other place that sells them?
Thanks.

Nope, and Pianotek is pretty strict on this issue. You could get a tech with an account to order one, but you will likely pay markup.

I think people spend way too much energy worrying about "flagpoling"; tuning pins and pin blocks are elastic within the forces encountered in piano tuning... not to mention the fact that everyone puts this kind of force on the pin when they tune.

Intentional tilting of the pin is a valid tuning technique, and that's what he's doing. Indeed, my piano's pins are so tight that fine tuning it would be impossible without intentional tilting! The important thing is that the piano stays in tune when you're done; that's all that matters.



I don't hear any cracking. Regardless, when pins do this, it says more about the pin block and perhaps tightness than tuning technique, IMO.



His unisons sound fine to me.

Thanks, Beethoven.

I wonder why Dan Levitan and PianoTek are not interested in selling to the general public. Are RPTs afraid that the unwashed will use this tool and take business away from them?

Dan Levitan is selling his tool through Pianotek. Pianotek sells piano supplies and tools to the trade. Anytime you buy stuff, you're paying retail, not wholesale. Bookstores, groceries, toy stores, gasoline, etc. etc.

What does RPT have to do with it? Nothing at all, if you understand what RPT means.

It seems that ever since Costco came along and started selling bulk to anyone who is willing to pay a yearly fee to enter the store, that the public thinks they are entitled to buy wholesale anywhere, anytime.

Most often, if someone asks "How much does it cost?" (it being a specialty tool, for instance) that they are not seriously looking at purchasing in that price range anyway.

Specialty tools often cost hundreds of dollars. If you think that is too much, get out your welder and weld one up for yourself. As long as you make it for your own personal use, this is allowed, as I understand it.

Mr. Goering, you are over reacting to my tongue in cheek comment. I am simply surprised that something as clever as the Levitan tool is difficult to buy. Also, contrary to your rant, I am not complaining about the price (which I do not know) - I just would like to buy one. Good grief!

Well, to be fair, it's not like they mass-produce these. But, it doesn't have to be difficult; ask a technician to order one for you.



You might not when you find out how much it costs... Considering that the online stores like Vandaking markup between 30-70%, depending on the item, you can expect to pay well over $400 for this Levitan lever.
