JOHN LENNON PLAYS IN 528Hz Solfeggio Frequency...

Funnily enough, as far as I'm aware anyway, the 528Hz reference above is for the key of 'C'?

Where depending on what you read usually equates to 432, 440 or 444Hz for 'A'...which I find all very frustrating considering;

In Western traditions, ‘A’ was originally tuned simply to the lowest note monks could sing in their Gregorian chants,

Some of the earliest surviving forks represented A between 400Hz and 420Hz.

If you’ve ever heard a Gregorian Chant, you’ve heard the Solfeggio frequencies, since this is the music they were most commonly featured in. The six core Solfeggio frequencies are as follows:

396 Hz

417 Hz

528 Hz

639 Hz

741 Hz

852 Hz
