A over middle C has been defined as many different frequencies over the course of classical music. it varied anywhere from a4= 392 hz to a4=465 hz and varied in some cases from city to city before becoming standardized. I fail to see how lowering it 8 hz imparts any kind of magic. also does nature use equal temperament or just temperament? I prefer not to ask the question of why notes are defined at the frequencies they are or why the ratio of a note from one octave to the next is 2:1. id rather race with the wheel given to me rather than to try remaking it.
