The downvote makes me think I offended someone. Sorry. Just finished playing in a jazz quartet tonight and the other guitarist knew much more than I about various tunings. He said I was correct about 444 hz being the correct tuning for 528. But one thing I had completely forgotten was the actual A note on a guitar is 110 hz when tuned to 440 hz. 440 hz is a harmonic. Great tidbit to know when talking about tension. So if your a guitarist, tune the A to 111 instead of 110 hz if you want to play in 528. I’m sure I would not be able to tell the 1 hz difference, but maybe others can. Kind of fun to see.
