432 Hz

[steevio]

When the note A is tuned to 432hz it can then be taken to lower and higher octaves giving the frequencies 27hz, 54, 108, 216, 864, 1728 etc. The note D also becomes 576hz which at other octaves is 9hz, 18, 36, 72, 144, 288, 1152 etc. The note E becomes 324hz (81, 162, 648, 1296 etc).

using 440, non of the notes or their harmonics are whole numbers apart from A !

Great topic. I was not aware of this at all, but i think it sounds like a hard job, tuning all your synths to work with the A4 frequency, but i'll give it a go

why is it a hard job mate ?

if you're using VA's just use master tune, and set it permanently at A4 = 432, you only need to do it once for all your synths.
if you're analogue, you have to tune your synths each time anyway.

i worked it out at 30 cents down, but that was using my ear, i dont know what the official detune is.

some interesting things there, still cant find that other link....will keep trying.

Gotta love cold hard facts!!!

you reckon whole numbers have a more significant resonance? either physically in the human body or otherwise?

All this maths is great, but it really has an element that I don't understand.

Why is a logarithm more 'musical' to us than a set of number increasing linearly?

Why does a tuning system have a different character when the base note is changed?

Maybe there's some people who can explain it.

I guess it's partly why I trust these cosmic frequencies.

Incidentally if you use A=432 then you get a csharp very close to 136.1 which is the earth year frequency.

Quite weirdly I did this exact tuning (12tET w/ A @ 432) for a track i did a little while ago, except I approached it from a different angle.. I was't thinking about this lower thing, I just wanted to use the earth year 'Sa' note. I recorded the track with normal concert tuning using a few c sharps and then repitched the whole tune at the end. Though I've since discovred slightly easier ways!

The harmonic tempo with this frequency is 127.6 I think (if you're using 136.1 as a root note at least), which weirdly is quoted by a few people as being a special tempo (I recall monolake mentioning a special bpm at 'a few decimal points below 128', though not in the context of the tuning discussion).

And also in a nice twist, I recorded a track using 126.22 as a root frequency with a bpm of 118.3, and when this track is played with my other one, if they are repitched to the same tempo they are harmonic, even though they use different scales and have different root notes. Crazy!

So, are we musicians or mathematicians again? I forget. Maybe they're just the same picture from different angles.

what a great thread! I can't wait to try this out when I get home
