Why 432hz Tuning?

Results of the scientific study referenced in billzame’s above post. Interesting, to say the least.  See below:

Results

432 Hz tuned music was associated with a slight decrease of mean (systolic and diastolic) blood pressure values (although not significant), a marked decrease in the mean of heart rate (−4.79 bpm, p = 0.05) and a slight decrease of the mean respiratory rate values (1 r.a., p = 0.06), compared to 440 Hz. The subjects were more focused about listening to music and more generally satisfied after the sessions in which they listened to 432 Hz tuned music.

Apparently, 432Hz, 528Hz and 7 others are naturally found in the earth's rhythms. They somehow correspond to our bodies as well. The former classics, Bach, Beethoven ect. made there music in 432 Hz. I do not remember the year that was given, but it was the French who started tuning their instruments in 440 Hz to make a difference to the Italians who shared a large advantage at the time. Somehow, the 440 Hz, although an unnatural band to us, seems to have won over and stuck. Whatever your opinion is, it does make for a real cool research project. There is a lot of science involved in tuning and at which frequency. I personally like to review the findings of how these different Hz cycles affect the psychic well-being or ill-being of ourselves as psychology is my field.

This is nothing but a silly wheeze. If the instruments had been tuned to 432hz, the resulting overtones would have been part of the recording. Simply electronically transposing the recording cannot reproduce something that isn’t there. The whole thing smacks of marketing superstition

As appealing as tuning into the frequency of the universe is, the '432 Hz is bollocks' argument is infinitely more persuasive.

That is why I call it relative pitch.
