I spent a few minutes putting together data I found on the MTU Physics website into a table. This will be super useful for those of you that want detailed control over your sound spectrums. The table is hosted on Google Docs and you can download and print it from there — it fits on a single 8.5″ x 11″ sheet of paper.
It includes all Western scale notes in equal tempered tuning based on A4 = 440 Hz and the speed of sound through an air medium being 345 m/s. It’s not guaranteed to work underwater or in space!

That’s pretty cool, thanks!
Many Thanks!
Thank you for the link, but this is WRONG. A4 should be 432 Hz. DO some research on older tables/solfeggio scales and you will see that over the last hundred years there was a movement to raise the frequencies to a harsher, less natural scale.
Hi Ralph,
This is an interesting point that you bring up. However, I use frequency tables primarily during the mixing stage to help locate and combat any unpleasant resonant frequencies. So if I know what pitch it is, I need to know what frequency that pitch is. We’ve been using the standardized A4 = 440 Hz for quite a while and most likely before the advent of digital synthesizers. So unless you’re going to retune all of your plug ins and change all of your tuners to 432Hz, then having a frequency chart of that type of scaling would not be useful.
So as far as 440 or 432 goes it maters not since this is the fundamental that from all the ratios of tuning are calculated. Based on about 10 years of researching this there are major issues when examining this outside of any kind of “victim mentality” which to my reasoning much of the resistance to 440 is coming from. So there are a lot of stories and hype about someone doing something to our frequencies. Although this may be highly possible and must not be rulled out as a factor in all of this the data shows that over the centuries composers, symphonies and instrument builders chose different fundamentals based on thier own understanding or intuitions.
The thing that must be addressed is ratio. The above chart as mentioned is from MTU Physics Dept. Although it is a valid, yet rounded up set of numbers that determine the tones and semi tones , it is implanting a set of irrational numbers over the perfect 5th, perfect 3rd and other such very important ratios. It is in these harmonic ratios that the real value in music lays… It has not been any fundamental which is the problem but more the ratos… The ratios represented in the charts are not harmonic with our body, or he micro / macro environments of our reality. To me this is the real issue underlaying tuning. When I have dug deeper into ancient sights the pure 5ths and 3rds and so on are found to resonate in ceremonial sites. It is believed and experienced by many that through the correct implementation of ratio that amazing things, including but not limited to out of body travel can be facilitated.
So many are jumping on the band waggon for 432 and 421… And although I do use these from time to time over 440 most of my guitars and synths are still locked into an equal temperment… So square roots Vs perfect intervals.
Your body was designed to harmonize with itself… Perfect ratios and not irrational ratios.
