Thank you, I'm fine although it's a total mess here in London.
Actually, I used to tune my guitar to 435 HZ and I think I will go back to that frequency or maybe even 432 HZ.
Have a nice day!

432 Hz is the frequency that all the other Solfeggio frequencies are based on. It's actually the center of it all. Check this out. It explains it in detail. Sonic Geometry: The Language of Frequency and Form

Thank you so much for the link!
