Didn't Chickering argue for A432 to be concert pitch? I had a Dutch composer playing in synch with 400 drones ask for A432.
It's not that A432 sounds worse, it's the instruments are designed to be at A440. Chickering designed some of his instrument to be at 432 and they sound fine.
A432 is said to be an extrapolation of a base earth frequency of 7.83 Hz. This guy I think is the one who came up with the frequency.
From wikipedia,
The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere.
For me, the scientific extrapolation without measurement is bogus. The nature of the universe isn't that consistent every second.
As piano technicians that deal with many different base frequencies in buildings, considering,,Hummmmm could be more important. 60 cycles a second is the frequency of the electric system in a house. I extrapolated that frequency and it seems to be a B. When I'm in a restaurant that has a lot electric humm that I tune along with, the B is the closest. The cooling fan frequencies are all over the map. Sometimes you can't turn off all the equipment and if 440 is not important,, why not adjust?
Maybe some of the techs with tune lab can give us some building frequencies to see if there is any consistency.

Subject: Requests for 432 and 417
Has anyone else noticed an increase in requests for tuning to A-432 or A-417 vs 440 lately? Some customers are following the thought process put forth by those claiming health related benefits, including Michael Terrell in his book "The Sound of Healing". I have had a choir and numerous individuals wanting their pianos at these lower pitches.
