Good to see so many other physicists on the forum. It is also nice to see actual measurements of the frequency responses of the struck body and plucked strings.
I tried a new v braced presentation series guitar last weekend. I was too timid to pull out my phone and make a direct comparison to the spectrum a similar older taylor. I did like the sound, similar to my cedar topped 716ce. The v brace hype is the work the Taylor marketing team. I can imagine the meeting where they discuss “how do we sell this?” And deciding that it would be easiest to redefine intonation. I am willing to cut Andy Powers some slack as a good employee following the company line. It seems to me that he was a little bit defensive in the long note. Please the quantum double slit experiment has nothing to do with thus discussion. There is no question about the phenomenon. Lifetimes can be spent discussing the implications. I dont care what google says.

Taylor makes well over 100,000 guitars a year. They have designed and implemented the most advanced guitar manufacturing techniques in the industry. They are extraordinarily methodical. They can spend unlimited amounts on R&D. They have a few years' worth of tone improvements to show for Andy Powers's involvement in their guitar designs. They've been working on this for months, and probably years. They are staking their reputation and success, to the tune of hundreds of millions of $USD, on this bracing redesign. But obviously random dudes on a forum who've spent 10 minutes reading marketing materials totally, absolutely, unequivocally know better. It's hilarious. Whether or not you like Taylor guitars, their tone, their playability, their marketing, Andy Powers's innovations, their "sterile" or "perfect" manufacturing, their use of computer-aided tools; whether Andy Powers has a physicist's understanding of sound and wood; none of this matters. Almost nobody on AGF is actually qualified to evaluate or denigrate these new changes outside of "they sound better/worse/the same to me." Everything else is bloviating. Not just the V-brace! I recognize a few AGF commenters around it.

Sound waves from the bass drum (when hit, or when excited by waves from the piano being played) combine with the sound waves from the piano, and the audible results are different based on how the drum is tuned (assuming the piano is constant). Whoa, what is that??

Hey now, that's not a very constructive way to communicate. If you believe someone else to be in error, that's awesome--and the only way we'll generate a dialogue--but rather than just pointing it out, it would advance the conversation if you were to upload an image of section 4.7.2 or type out the relevant quote since, for some bizarre reason, other AGF members keep recalling the copy of Contemporary Acoustic Guitar Design and Build I had checked out from the library

However, that brings us immediately to the next (and probably more important) question: you can tune a drumhead by turning a bunch of screws. But how does V-bracing tune the guitar top? This was never explained by Taylor. It was only stated that the top moves more orderly, that the vibrations are more limited to sideways motion etc. But how does this tune the guitar top, systematically and principally, for every single V-braced factory-built guitar? Now THAT’s what I would like to understand. Grafted walnut. American Walnut trunk with a European Walnut branch grafted into it. Wait a 100 years and the branch is big enough to build a guitar from. Cool huh? But don’t order such a guitar when you’re in a hurry .

I brought up the double slit experiment because as I wrote " when the experiment is done with SOUND WAVES" and or two sources instead of two slits" ,and not light, we get constructive and deconstructive interference which imo is pertinent to the conversation as various pole phases in body motion act as localized drivers which gives rise to the possibilty of either constructive or deconstructive frequency interactions within vibration patterns.

- Michaelson & Morley were wrong - Photons don’t exist, light has no dualistic character - The universe moves at the speed of light. The above three points solve the whole double slit discussion too, and also the Einstein Rosen Paradox. I’ll give a 90 minute lecture about this in Glastonbury, this summer. It’s going to be fun. OK, back on topic now. AP and V-bracing.

It is also one of the reasons why it’s so hard making a good audio recording of an acoustic guitar. Different parts of the sound come from different positions, so it’s as if the sliders of your equalizer make random jumps every time you move your microphone. However, I fail to see how this fits into the Taylor in-tune-ness story. The only way to reduce this interference effect, is to make sure the top can only move in and out as a whole. That’s the low E string. Higher notes will always cause bipolar modes and higher, along with the inherent interference effects. V-bracing will definitely modify the response curve, and hence the tone, but I see no reason whatsoever why this would improve “in-tune-ness”.

This is wonderful. Who would have thought that Taylor v bracing would lead to einstein and quantum physics and the dualistic nature of light being discussed???
I reckon that to solve the grand unified theory problem, Taylor needs to release the Z class bracing next year an d say how it is even better than v class bracing at intonation LOL

No offense, I love these V-bracing threads. The best threads on the AGF in a long time!

you know it's funny, I was reading articles the other day about this Dutch physicist who apparently did stints on "Baywatch" , has interesting theories, the real funny thing is you're that Dutch physicist , the crop circle guy, cool beans dude... the gravitron wave that came by, it's F sharp , check it on your tuner at 432, surely it means AP is wrong
