There is a tuning for middle C that fits A-432 harmoniously. Maybe even perfectly. That tuning is C-256 Hz. This has been the scientific standard for middle C for decades.
Current standard is C-267 plus something past the decimal point. Just another number to defy the natural order.
I posted a video presentation on Tonic Power with Middle C.
I have tuning forks from scientific surplus that are 256 and 128 Hz. Also not long ago I got a tuning fork that vibrates at 432 Hz.
Maybe we are starting to come full circle here.
