I was once told by a first chair violin player during a string session I was recording that the reason string players, violin players in particular, want 441 is because of the physics of the strings when they are bowed. When the string is initially put into motion by the bow the frequency is just a bit sharp from what it will settle in to after it has been played for an instant. Much like piano strings behave, with the attack being a tiny bit sharp in frequency but then it settles down a bit right away leading into the sustain. I was told that the reason string players, violin players in particular, are so sensitive to this phenomena is due to the fact that their violin sits right next to their ear and that initial attack is loud. Hence, for that brief moment when they first start to bow, the violin sounds sharp to them compared to, say, the piano. Requesting 441 pitch, I was told, soothes their egos, makes them feel powerful and keeps them happy. Mind you, this was the '70s, and I was working with session players, who were notorious complainers, so who knows if this is actually true. Fun to think about, though.

Steve, actually American oboists play French oboes, mainly F. Lorée, Paris if preferences haven't changed. There are two lengths of the "staple" that the cane is bound to and the overall length of the reed has some latitude.
It's common for ensemble musicians to play a little sharp in order to cut through and be heard, particularly with the higher, more soloistic instruments, that has been offered as the reason for ever rising orchestral tunings. I'm not sure about that but indeed higher equals brighter.
I don't know if you looked at that "History of tuning standards" but it's interesting to note national and international standards tended to be set by "amateur musicians" who were also technologists or theorists. Probably because they were more likely to get a seat at the table for such conclaves rather than musicians. However the American standard of 440 was set by JC Deagan, the percussion instrument maker who also made tuning forks.

I tune for a festival in an outside amphitheatre on the Mediterranean coast. It's run by an Austrian lady who was shocked that I should tuned at 440 with an orchestra visiting from Vienna where they're at home with 444. I refused 444 and met a compromise at 442. Playing outside in the evening in any case isn't conducive to perfect instrumental tuning
https://www.youtube.com/watch?v=XHxsZg6nhtk
It's a Yamaha C3 which at ground level sounds as good as the recording
https://youtu.be/RXymuml03pE?t=1341 but from the upper terraces the instrument . . . sounds like a Yamaha and painfully so. Would taking it down to 440 remove the sort of Yamaha brittleness that I don't like?
Incidentally thanks to all contributing here as I've been puzzling how to set the temperament I use by ear and have given focus to C2 E3 and E4 and neglected the harmonics on F2 F3 and A4 both of which become interesting being near perfect sweet thirds.
Best wishes

Mr. Norsworthy --
Both Kawai and Yamaha ship at 442 for the purpose of stretching the strings and giving them time to settle in during shipping. Both are scaled to 440. I would guess that other manufactures follow a similar principal.
Bösendorfer, on the other hand, have forever scaled their pianos to be tuned to 443, and they really do sound weak when tuned to 440. It's the only piano, that I am aware of, that is deliberately scaled for anything other than 440.
In 1859 the French government passed a law setting A4 to 435Hz. 435 Hz was also the frequency set in the Treaty of Versailles in 1919. In 1936, the American Standards Association recommended that the A above middle C be tuned to 440 Hz. This standard was taken up by the International Organization for Standardization in 1955 as Recommendation R 16, before being formalized in 1975 as ISO 16.
The choice to tune to other than standard or scaled design is purely owners choice and varies widely all over the world. Nevertheless, most pianos sound best when tuned to the frequency for which they were scaled.
Regardless of standards, yes, many organizations choose to tune to frequencies varying anywhere from 415 to 466. Pity the poor woodwind and brass players that have to modify their instruments in order to accommodate those extremes.
That said, the note that a tuner uses to set A4 aurally, to whatever frequency, is still probably F2.

Hamburg Steinways, Bechsteins, and most German Pianos at the factory: 442 or 443
Kawai at the factory: 442; most of Japan for that matter
All Central European Orchestras are either 442 or 443,
and most major US orchestras are now at 442 including: NY Phil, Chicago, Boston, LA Phil, Houston Sym
At LA Phil auditions, they sometimes make the instrumentalists tune to 442 before they walk onto the stage.

There really is no de facto standard. Whatever standard organizations are using doesn't matter outside their walls. Unless you're suggesting that one should tell the organization you're tuning for that they're wrong and need to change their tuning standard.
Besides, there have been wide discrepancies in what people are saying various orchestras/organizations are tuning to and what they're actually tuning to. People were reporting that the Boston Symphony Orchestra was tuning to A444 when I know for a fact (because I was tuning for them at Tanglewood) that they were using A441.

Hi Norm.
You are probably aware that the de facto International Standard is now 442. All the major orchestras are on 442. All the European piano makers are tuning at 442.

Hi,
My name is Norman and I am a pitch floater. Thanks for letting me join this group.
On the serious side, in my university work, the only place I really strive for A440 is on the performance pianos. Voice studios receive a tolerance of plus or minus 4 cents depending on Fall or Spring semester. I have heard operatic sopranos with a wider vibrato than that pitch range. I have even been known to float in the Oboe studio and have not received a complaint. My goal is to have the piano be as stable as possible for as long as possible. I can relax knowing that at some point in the year the piano passes A440 on its annual journey and pitch cycle.

Speaking of tuning forks: I consider the gold standard of tuning forks the John Walker nickel-plated A440. Weighs 4 ounces, twice that of their blued forks, and it sounds loud and long! It's still sold at Vanda King's. Regards, Norman.

I have practiced PF (Pitch Floating) for decades. I can count on one hand the number of clients (and even concert venues) that require a specific pitch level for the tuning session. I have not used a "fork" in at least twenty years, since the electronics available are far more convenient.
That said, I remember a short period when I was using a Sanderson Accu-Fork (still in my drawer with the Electro-Fork) and it had unknowingly gone berserk due to a low battery (at the time I didn't realize that could/would happen). It went wildly sharp and I started pitch raising the piano. But something was nagging at me that it didn't seem right. I now forget precisely how I figured out what was going on, restarted the tuning using my fork, called the "Doc" to discuss it and he said: "Yeah, that'll happen..." We laughed and that was when I decided to put it in the drawer.

Yet there seems to be another issue: piano tuners may not have researched the scientific articles on the characteristics of tuning forks. Research shows that the tuning fork is virtually free of any overtones until we get to the ratio 25/4 above the fundamental. Look up the article on Wikipedia. That overtone is not falling on anything near a ratio we may want, and that overtone is at least 40 dB (100x) lower in magnitude than the fundamental. So much for IH! There is also a research article you can find that has a mechanical / acoustic model done in Matlab which correlates to all measurements, so I assume that the researchers have beat this subject to death over the years.
The conclusion I have from all of this is to use high tech like I posted regarding what a sophisticated app like Pianoscope which can generate the tones we want at the frequencies we want with the overtones and IH that we want. This can be the general solution to the problem.
Best regards,
Steve N.

Ryan said: "Full confession: I almost always float the pitch if the shape of the tuning is overall good if the pitch is within a couple of cents (etc.)"
Ryan, I do the same and other tuners have made the same "confessions" to me over the past few years. Traditionally, for straight aural tuners, the tuning fork was our pole star. And still, at a point where even if you are tuning aurally, there are electronic means to quickly measure the full spectrum of an instrument to a) see how close the the piano is in tune with itself, and b) find the relative frequency range of the tuning. You say "a couple of cents" but then expand it to possibly another couple of cents -up. Which I agree with.
I think it's worthy of a thread to bring the practice out in the open. "A-440" at this point is something of a talisman for us that has prohibited us from talking about the flexibility that we can exercise intelligently with our current tools that can help us create more durable tunings. Another factor to consider is ambient room temperature in where to center A4. One thought I had at the beginning of this discussion was to wonder how many people check their A4 at the end of the tuning. Air temp of +/- 2 degrees can change the tuning enough to show up on an F2-A4 test. It's worth thinking about the conditions the piano will be used if it is in a church or performance venue for example.
I think it's time to come out of the closet regarding floating the 'A' I'd like to hear about other's practices or guidelines.

I rarely tune aurally any more, so setting A4 to 440 is rarely something I think about since I use an EDT. (For the record, I passed my tuning exam, years ago, aurally using an A4 fork and without the aid of an EDT.) In any case, because of this thread I went back and looked at my notes about setting the temperament aurally. I like Kent Swafford's sequence. And sure enough, he says to use F2 for the comparison note when setting A4. Not F2. Thanks for the correction.

Yes Maggie! You got what I was trying to get across. One of the confusing aspects of discussing tuning is the discrepancy between Beats/hz and cents. It's important for us to remember that cents double with each octave up. Thus one beat(hz) is about 4 cents at A4, but one beat is 2 cents at A5 and at A6 beats and cents are about equal.
The discussion that evolved from my original post, shows that there is still confusion around this topic even among seasoned tuners! That's mainly why I brought it up. This came up at a meeting where we discussed transferring A from the fork to the piano. People are tempted to use F3 as the test note because it can also be played one handed with A4 (if you can reach a 10th! I barely can).
Norman also did a good job describing the discrepancy that happens when using F3 instead of the proper F2. If we had a tuning fork that had the exact inharmonicity of the A4 on the piano, then there wouldn't be the discrepancy.
I don't know if people were making typos, but I was very surprised to see others mention using F3! For instance, Wim said:
Ryan
I don't count beats, per se, when transferring F3 from A4. I compare the beat rate of F3 to A4 on the piano with the beat rate of F3 and the fork. It really doesn't matter what the beat rate is, as long as the two match. There are no partials involved.
I completely agree with what you are saying regards the difference between counting beats and comparing beats. Well said. But don't you mean F2? Are folks really using F3 or do they mean F2 and are just getting their octave numbers mixed up?
Thanks, Parker, for mentioning B1. When you mentioned it, it sounds familiar, but I haven't tried it in a long time. It's good to have more than one test available, as one might give a clearer signal then the other.
Honestly, I almost always use an App when setting pitch, even though I prefer tuning the majority of the piano aurally. However, after this discussion, I'm going to use my fork the rest of the week for the practice. Full confession: I almost always float the pitch if the shape of the tuning is overall good if the pitch is within a couple of cents. I particularly don't mind if the piano is at 441 in most situations.
Peter Gray mentioned the Electro Fork. Using a standalone electronic tone generator is probably the most sure-fire way to get a good pitch score on the exam. Examinees can get very flustered over their forks, and whether they are properly calibrated or at the right temperature. One examinee brought her fork into the exam room in a glass of ice water because she thought that was the most reliable way to reproduce a specific temp!
Reading a previous thread, someone had recommended Rick Butler's YouTube video about setting pitch using a Korg tone generator and the beat that occurs in the 3rd partial that you can use to your advantage. It's excellent! https://youtu.be/TTG3KyPmyog?si=OP28WpAAS_8ROGBu
IMPORTANT: when we are helping people study for the RPT tuning exam we need to make sure we get this right: F3 is not the correct test note!

Thanks, Norman, for sharing all that. I wasn't thinking & you helped me remember & re-understand things.
I think Ryan wants to know why there is a discrepancy between his machine and his ear regarding the second partials of A4 (fork & piano) and the fourth of F3.
He wrote: "I'm thinking it must be because the second partial being 2.6 cents flat means the fundamental will be closer to 1.3 cents flat, which was pretty close to my results."
That sounds right to me. Ryan: How about you measure other partials involved? I bet that will give you more, useful information. I think you're right, but I am obviously being a bit slow on this one. 😉
(I shouldn't post when I'm tired; I'll say things wrong so please correct me when I do that.)
Interesting topic! Thanks, Ryan!

Geoff and Wim, I am 100% with you on setting A4 from F3, using an equal beat rate for the F3 note to the A4 fork versus F3 note to the A4 note. (In my case my temperament octave is C#3 to C#4, but for all intents and purposes we are the same.) Unfortunately, it sounds like all 3 of us are wrong! Sorry. We are using/tuning a tenth, which is a 5:2 interval, so the coincident partial we are listening to is at A5, not at A4. If there is any inharmonicity between A4 and A5, which there will be, that will push A4 slightly flat. That is because the second partial of the tuning fork supposedly has no inharmonicity relative to A4. Sometimes I use the F2 to A4 interval rather than F3 to A4, based on the piano and what I hear, which is a 5:1 musical interval -- and that is subject to possibly subconsciously listening to the 10:2 interval (with coincident partials at A5) that Bill Bremmer talks about. Regards, Norman.

For me, I use my A4 fork to tune A4 as close as I can. I then compare the fork to F3 to see what kind of beat I get. Next, I compare F3 to A4 and start fine tuning A4 until the beat comparisons between F3 and the fork and F3 and A4 are the same. Doesn't make any difference where F3 happens to be as you are only concerned with the comparison beats being the same. In fact, it's OK to detune F3 in order to get a beat that is easier for you to hear when doing the comparisons. The important thing is to wind up with the beat rate between F3 and the fork and F3 and A4 being identical. When both comparisons are the same, A4 and your A4 fork will match without any movement.

Fellow tuning nerds,
The title should have read test NOTE not test NOT. Oh well.
Sometimes people will use F3 to transfer A4 from the tuning fork to the piano, instead of the traditional F2. While F2 beats with the fundamental of A4, F3 will beat with the 2nd partial of A4. I was taught that using F3 will result in a flat A.
When my piano is tuned to A440 the second partial of A4 measures 881.25 hz which is about 2.6 cents sharp. My hypothesis is that if I match the beats from the F3 - Afork to the F3 - A on the piano I would end up with A4 being 2.6 cents flat. This is because the fork, having virtually no inharmonicity, produces a second partial of 880. I should have to lower A4's second partial by 2.6 cents to make the beats match.
However...in real practice when I used beat matching to use F3 to set pitch, my A only came out about 1 cent flat, much less than I anticipated. I did this a few times, with basically the same result.
I'm having trouble wrapping my brain around why it's only a cent flat when I match the beats by ear? I'm thinking it must have to do with how hz and beats change with each octave. I'm thinking it must be because the second partial being 2.6 cents flat means the fundamental will be closer to 1.3 cents flat, which was pretty close to my results.
This was using a calibrated Johnny Walker blued tuning fork and Tunelab for measuring.
Am I thinking about this correctly?
