I read a book by the famous flautist James Galway. He said that it is not true, even today, that A440 is a standard pitch. Orchestras are highest in Germany and lowest in the United States.

Pay no attention to that stuff about 432 being a healing tone constant in nature. It's 432 beats per second, and if mankind had made the length of a second longer or shorter than it is, then the number 432 would change.

Has anybody else noticed that 432 = 36 dozen?
