Dear M. Ted I understand what you are saying. But what I was saying is that; our whole system of music, which is limited to twelve notes, is out of tune, because of tempered tuning. I disagree when you say that someone figured out how to tune a piano. A perfectly tuned piano, with everything tempered, sounds, to me, awful, but I live with it, but it's still awful. And the practice of temper'd tuning has casued all of the stringed instrument players to change the way they play so ... they now play out of tune also. And I have to laugh at the 'modern contemporary composers' who write all this discordent experimental crap and talk of each other as being such dare takers when all the time they are limited to a twelve note system, tempered no less. Sincerely, toad
