Why 432hz Tuning?

@antigrunge2. 
“If the instruments had been tuned to 432hz, the resulting overtones would have been part of the recording. Simply electronically transposing the recording cannot reproduce something that isn’t there.”
Thank you for this great point.  
You are correct in the inherent silliness of electronically changing the pitch of a recording after the fact.  
“Ooooo, now we can listen at 432, honey!”  
🤣🤣🤣

Seeking out recordings that were actually recorded in 432, okay.  
Now we have something here.

I suspect that convenience, not wanting to change from the norm, and a sense that the 432 argument is “just woo woo gibberish” has kept us from adopting 432 as the norm.  
Based on the evidence, I don’t see why we wouldn’t just make 432 the standard.  
It seems to be what we like more.

Thank you for the detailed response.  
Unless I’m missing something here, manufacturers of woodwind instruments could make very simple, very practical, very small changes to the construction of the instruments wherein anywhere from 432 hz to 440 would be easily attainable on the spot.  
At that point, considering all the other instruments can be tuned to 432, an orchestra could play in 432.  
Am I missing something here?

@frogman “…this change would render every non-string orchestral instrument in existence obsolete.”

If woodwind instruments can be tuned, why can’t they be tuned to 432 hz?

@frogman Gotcha.  
Thanks again for another detailed response.
