440 vs 432

[Bob Hoffnar]

I just checked the overtone series using 512HZ as a base. At no point does the frequency 432HZ occur naturally in relation to the frequency 512. It has no relation to the note A unless you use an arbitrary tempered tuning. When you check the numbers and the actual physics of sound this "fact" you quote turns out to be completely false.

I'm not speaking of overtones. I have a tuner app on my phone called "Tuner-Pitched" that is a chromatic tuner (equal tempered). It has a preference option to change frequency of A from 440 to anything. I set A to 432. When I tune my 6 string guitar, the low E reads 81.0, A=108.0, D=144.0, G=192.5, B=243.0, E-324.0.
My DX7 keyboard has a pitch adjust on slider. If I adjust DX7 so that A=432, then the middle C=256.

I got it it now. The misunderstanding is that your tuner is using equal temperament. There is nothing natural about tempered tunings. Tempered means adjusted for practical purposes. It was invented by humans so that we can play music that has complex harmonic content. Chords that modulate. When you are talking about how things resonate naturally the whole 442 thing falls apart.

Frets on a guitar are laid out to play equal tempered notes. Pianos have tuned equal tempered since they were invented.

The tempering of 2 or 3 cents wont make one whole cps difference except in higher octave ranges.
