![]() ![]() Without going too far down this rat hole, this theory says that tuning all music to 440 Hz turns it into a military weapon. It is said that the Rockefeller Foundation had an interest in making sure the United States adopted the 440 Hz standard in 1935 as part of a “war on consciousness” leading to “musical cult control.” There is allegedly something sinister and evil about 440 Hz. The more radical among middle “A” haters insist that the true frequency should be 528 Hz because it’s a “digital bio-holographic precipitation crystallization miraculous manifestation of diving frequency vibrations.” I have no idea what that means. They point to how this pitch can be connected to everything from nautilus shells to the works of the ancients, including the construction of the Great Pyramid. Others believe that the correct middle “A” is 432 Hz (also known as Verdi’s A) because it has “a pure tone of math fundamental to nature” and is “mathematically consistent with the patterns of the universe, vibrating with Phi, the Golden Ratio.

In fact, they consider the 440 Hz middle “A” to be an abomination against nature. In fact, there those among us who vehemently disagree with this standard. Weirdly, no one can say for sure why this frequency was chosen in the first place. This tone standard is now universally accepted, which is why a piano in Toronto sounds exactly the same as a piano in China.

Regarding how accurate are digital tuners, they are based on quartz crystal oscillators that usually are easily accurate to 50 parts per million so, essentially, they are very accurate. For the final tuning, I did let it cool down between grinds and checks just in case the temperature had a significant effect. It's certainly not changed it noticeably. I was easy to keep both tines the same length by eye and the sustain on both seems the same as it was before. It wasn't touchy either, it's not critically minute amounts taking off, just don't go daft. It's not rocket science or even heavy engineering. Just got my guitar chromatic tuning meter and used my bench grinder to take equal amounts off the tines' ends a bit at a time until the frequency was right. ![]() Just adjusted two A tuning forks I had to A#/Bb for my trumpet. The tone probably isn't as pure, and tape will eventually age and wear, but this quick fix should work well enough until my next trip to a good music store for a better quality tuning fork. The fork also now sounds good when played simultaneously with an mp3 of a 440 Hz tone to check for beats. A little more fine trimming of the length of the tape with some sharp scissors, and I got the fork to measure within +-1 cent of 440 Hz, as measured against several calibrated iPhone tuners (both dial and strobe). Wrapped the new lengths of tape on the fork tines, and the fork rang 3 cents flat. Then I cut some tape strips about 9/29ths as long (actually a few mm longer). So I removed those pieces of tape and carefully measured them. ![]() That also lowered the frequency, by only a bit too much, to 20 cents flat. Next I tried a couple strips of masking tape wrapped around the very end of the each tuning fork tine. Two big rubber bands on the tines clearly lowered the frequency. So I played science student, and tried the experiment. I found a quick-and-dirty temporary solution.Īs an online education forum suggested, a interesting school science experiment might be to see if adding weights and changing their position on a tuning fork will change the frequency of the fork. ![]()
