violins88 Posted October 18, 2022 Report Share Posted October 18, 2022 Has anyone seen this: David Langsather tuning by ear. Is it valid? He says he hears a frequency like 179 Hz when he taps the sound post. I don’t think that’s possible. Maybe a subharmonic? Quote Link to comment Share on other sites More sharing options...
JacksonMaberry Posted October 18, 2022 Report Share Posted October 18, 2022 I haven't seen this before, and I don't recall seeing anything about tuning the frequency of the post before. Did I miss where he said what the goal of doing this was? I haven't messed with much with posts other than getting them to fit well in the right spot, but I have played with making them out of a few different materials. I didn't notice as much of a difference as I had expected with a maple post or a Paulownia post Quote Link to comment Share on other sites More sharing options...
Don Noon Posted October 18, 2022 Report Share Posted October 18, 2022 Folks can get all kinds of crazy ideas in their head. Tuning things to matching frequencies seems to be a big attraction; no theory or proof needed. He's using a long length of soundpost material to tap a short piece. What's to keep the long piece from vibrating? In any case, there is no mode of a free soundpost that would be anywhere near 179 Hz. Bonkers.

jacobsaunders Posted October 18, 2022 Report Share Posted October 18, 2022 The next time the sales rep comes around with all his pegs and fingerboards and stuff, I will have to drive him bonkers tap tone testing all of his soundposts Quote Link to comment Share on other sites More sharing options...
Mr. Bean Posted October 18, 2022 Report Share Posted October 18, 2022 Should be 432Hz! (the "ground frequency of the universe", according to the mystic circles and sources that tend to generate complot-theories as well!) Quote Link to comment Share on other sites More sharing options...

FiddleDoug Posted October 18, 2022 Report Share Posted October 18, 2022 I'll call BS on that! He's either got the SP in the violin, which couples it to the plates, and changes the composite frequency, or he's holding it in his fingers, which will also change the frequency. In either case, it's not a valid way to do things. Fit and placement make a lot more difference than any small tone change in the soundpost.

(the "ground frequency of the universe", according to the mystic circles and sources that tend to generate complot-theories as well!) We will have to start using rubber toothpicks instead of the standard spruce soundpost. I tested 2 soundposts, and the lowest bending frequency was 8400 and 9390 Hz. Rough theoretical estimate shows that's about right. And the air wavelength of 179 Hz is nearly 2000 mm, so even if the soundpost DID vibrate at that frequency, it wouldn't be able to radiate any sound that you could hear, since it isn't a monopole radiator. And in the assembled violin, the only modes below 190 Hz are the B-1 overall bending mode (includes neck and scroll) and some tailpiece modes. And the lowest played note is 196 Hz, so anything much below that is ignorable anyway. This is like logically refuting statements yelled by the bum on the streetcorner.

JacksonMaberry Posted October 18, 2022 Report Share Posted October 18, 2022 I will agree that it doesn't make much sense to be, but I'm sure we can all at least be more civil about our disagreement.

Shelbow Posted October 18, 2022 Report Share Posted October 18, 2022 Your tools have to be in tune as well. If your plane doesn't ring at A 440 when you bang it on a desk are you really a violin maker? Of course don't forget your 415 plane if making baroque instruments.

I guess what I'm suggesting is it takes rather little effort to say from a position of authority, which you enjoy, that something is misleading or wrong without being deliberately unkind about it. Really, it's easy. I'm not asking anyone to polish the guy's buttons. I've already agreed it seems more like magical thinking than anything else. At the end of the day he's entitled to it, and there's nothing to be gained by ridiculing him on a public forum. Quote Link to comment Share on other sites More sharing options...

Andreas Preuss Posted October 18, 2022 Report Share Posted October 18, 2022 I made it half through the video got extremely bored and then I channel hopped to the sound demonstration of mr. Langsather. He doesn’t even know the difference between Tchaikovsky and Massenet Quote Link to comment Share on other sites More sharing options...

It would be easy to ignore unkindness when I see it, and even easier to be unkind myself (God knows I am sometimes). But I'm trying to be better. Trying, at least.
