The A/LA 432Hz unweighted

For those who wish to tune their instrument to a lower tuning than the traditional A440Hz. There is a big debate in some circles about the tuning of the note A and many who believe music written in the lower 432Hz is more healing in its effect. While there is no evidence to support this claim, it is a fact that much early classical music was written in a much lower tuning than the 440Hz used as the International Standard Tuning today.
