Tuning A to 432 hz may yield the answers to the question that so many people ask themselves - why does my music not feel the way that I hear in my head? Why is it that so much of the music that I hear out in the real world feels so...plastic-y and false when I know it could be so much more? Actually, no it won't yield those answers. It's basically just a big new age circle jerk. But the weird internet obsession with A=432 does bring up some interesting questions about the history of how we got to our current standard, A=440, and why some people might dabble in lower tuning systems.

I don't know enough about registration and the soprano voice, but something tells me that the register shifts aren't the same among all singers. That said, an interesting idea, and not nearly as idiotic as some of the other ones on their page) http://www.schillerinstitute.org/fid_91-96/fid_911_jbt_tune.html PITCH INFLATION https://www.linkedin.com/pulse/great-pitch-inflation-marilee-haraldsson HISTORY OF PITCH http://capionlarsen.com/history-pitch/ CHANGING PITCH OVER TIME http://www.mcgee-flutes.com/eng_pitch.html SUPPORT ME ON PATREON http://www.patreon.com/adamneely FOLLOW ME ON THE
