Can someone tell me how to tune a guitar to 432hz? I want to try it on my guitar.

i really don't like 440hz. i rarely listen to music, especially popular adio because it feels quite soulless which i find disturbing.

The radio in my truck stopped working and I nearly freaked out. Till my friend disconnected the negative battery terminal for a few moments and it worked again.

Hi,
Wow, this was a cool thread!! I'm sorry to reply so long after the last previous post by Gem, but as an engineer and ex-musician I found it fascinating.
I'm not trying to down anyone's theory on possible conspiracies, but here are the practical reasons that 60 c.p.s. is a good line frequency.
First, let me add the caveat that 60 c.p.s. wasn't and still isn't "universal". Many countries in Europe and Asia use 50 c.p.s. / 240 volts. (One Phase to Neutral.)
In fact, up until recently Japan had one part of the country 50 Hertz, one part 60 Hertz. Which made receiving Analog T.V. from Tokyo a nightmare, because T.V. transmitters and receivers use the line frequency for the Vertical Sync Pulse. (Imagine watching Godzilla with the screen flipping vertically, 10 times per second.)
Line frequencies where all over the board until about 70 years ago. The "standardization" came at first, due to long distance transmission loss, A.C. motor rotational speeds, and........light bulbs.
Using D.C. was not an option due to resistive losses. High Frequencies were a problem due to radiational , inductance, and distributed capacitance losses,........ as well as the fact that the frequency is determined by the speed at which the generator rotates. High speed mechanics equals high maintenance, high frictional losses. (Also distributed capacitance in generator or motor windings decreases coupling efficiency.
So,....a low frequency was needed. Enter,....the Light Bulb.
When A.C. first replaced D.C. as the standard, many line frequencies were 25 c.p.s. This produced an annoying, (sickening), flicker due to the heating inertia of tungsten, and the processing hysteresis of our eye / mind interface. So experimentation resulted in 50 c.p.s. being fast enough to overwhelm our eye to mind processing speed. (Barely.)
(Guys, this is a very simplified explanation, the frequency standards were all over the place for quite a while.)
Then,....comes A.C. motor R.P.M. rotational speeds and torque conversion. As I mentioned, higher frequencies result in more losses. Real low frequencies require extremely large cores for permeability, and high inductance windings. (Miles and miles of wire.) A.C. motors utilizing the materials available then, had a peak efficiency around 50/60 cycles.
The standardization came because a motor's rotational speed is determined by the line frequency / number of poles / number of phases.
60 c.p.s. on a two pole, single phase motor results in 3600 r.p.m.
Now comes some great Time Standard "conspiracy" material. Time is based for the most part, on multiples of 60. (60 seconds / 60 minutes / etc.) This has an additional relationship to the 360 degree relationship of a cycle / circle. (6 x 60 = 360.)
A.C. voltage is a sine wave. A sine wave is just a circle, (cycle), starting at one point in time and ending at another. It contains 360 degrees. (6 x 60)
Now,...at 60 cycles per second line frequency,...you have a frequency that is both a direct integer of our time standard (60 seconds), and a direct integer of our circle / cycle geometry (360 degrees).
This makes mathematically predicting rotational speeds as related to time, and rotational position as related to time vs Degree of Arc, very simple. A great aid when it comes to motor design.
So basically 60 cycles per second, is the "almost" standard in part, because of a great Illuminati conspiracy to make the time standard 60 seconds. (THOSE BASTA***!)
Stay tuned for the my genius thesis on 440 vs 432 c.p.s., here on One Eyed Jack Radio.

mjlabadia, how can I possibly know what my music (the music that I make) is tuned at?
I'd be happy if you could tell me!
There's a link to my Soundcloud on my profile. I'm not sure how hard it would be for you tell.
Thanks in advance!

I sent this info in a private message to Lighthead, I'll post it here for others if they need it.
A small investment of about $30.00 U.S.D. at any music store will get you a guitar tuner. They usually have an on-board mic / transducer, as well as a phono jack for electric. They have a a + / - minus scale type meter and a key or string selection, which will allow you to tune each string on the guitar.
It is best to use the 2nd harmonic of each string, as it is almost a pure sine wave, and much easier for the Frequency to Voltage converter circuit to phase lock to. An open string pluck has too much harmonic information. (Just lightly "touch" the string at the 12th fret, don't fret it or push down, with your left hand middle finger, and pluck with your right, and you will get the 2nd harmonic.)
Or, there are many online guitar tuner apps on the web. Some of them are just plucked guitar samples or tones at the same frequency as each string,....some use your computer microphone and a metering app.
Then of course you can use the "poor man's" method of tuning to a song you know the key for, and your certain is A / 440. (Many songs ARE NOT tuned to A / 440!!) Especially before the days of digital recording, time quantizing,......and the much over-used Auto-Tune / Pitch Correct.
In the 70s and early 80s,....You will find many of the songs to be off from A / 440. If a song's tempo was found to be a little too edgy, or dragged a bit, but you didn't really "feel" it until after you laid down all the tracks,...........all multi-track decks had a vernier speed adjustment.
Say you're in pre-production,...or mix-down,.....you're kind of standing outside the song now. You have a little better view of it's feel to a listener. Much more so then when you're laying the tracks down.
You can't go back and re-record,....studio time is expensive,...you have a contractual deadline,...etc. (In the industry, like every other business,...... everything is budgeted to the penny.)
So you just make a slight adjustment to the tempo using what has been incorrectly termed as the "pitch control" on the 24 / 16 / 8 / 4 / 2 track deck, depending on what decade you were recording in. ( Really just a tape speed control.)
You couldn't take it too far because as well as adjusting the tempo, it did adjust the pitch or tuning of the song. Too fast and you sounded a bit like Alvin and the Chipmunks. (Yes, that's how they created the chipmunks cute voices!!)
Another trick was if the singer was having a difficult time with the higher registers, you could slow it down, thus lowering the pitch, so he / she could lay the track down, then bring it back up to normal again.
A good example is the studio version of The Song Remains The Same by Led Zepplin. You can tell this is exactly what was done by the speed of the tremelo in Robert Plant's voice. Unnaturally fast, and the Chipmunks' sound.
So,....honestly a great many songs are quite off from A / 440. Cool theory about the 432 C.P.S. though. I want to find out more about that.
