Since I wrote this 3 years ago I have expanded on my knowledge of 432 and made a more comprehensive work around tuning in Ableton Live, theory, and using third party plugins. Check out the three articles below for a deeper look at 432:
Lately I have heard a lot about 432 tuning and wanted to try it out. I’ve been experimenting with returning in Ableton Live. Before that lets review about the idea behind 432 versus 440 tuning.
The idea is that the natural world resonates with 432 and it’s tuning more than 440. This get very theoretical, but let me put it this way. Tuning was histrionically free game. You could tune your orchestra up or down. There was actually a problem called “pitch inflation”. Basically the higher the tuning, the sharper the sound. It would also make it sound louder to the listener.
At some point the decided to standardize it. I believe 440 was chosen because it’s mathematically easy to deal with. 440 x 2.5 is a lot easier then 432 x 2.5 Read more about the history here: http://en.wikipedia.org/wiki/A440_(pitch_standard)
Now 432 does seem to have a lot of resonances and correspondences. I am still exploring this deep subject, and am taking it with a grain of salt as well. What I can tell you is this. The lower the tuning the more calm and lush the music sounds. I actually really like 432 tuning because of the quality of the harmonics and resonances. Feel free to comment below on this thread to share your thoughts. I would love to hear them.
Also here is a picture of a water image at the different tuning.
